SUGGESTIONS TO IMPROVE THE TI NSPIRE CAS OS 2.2, DIC 2010

[elkar]

Hello

SUGGESTIONS TO IMPROVE THE TI NSPIRE CAS OS 2.2 DIC 2010

Many users of TI-89 CAS and PLT-200 CAS are still awaiting for some
of the following capabilities in the TI-NSPIRE CAS:

1) Enabling or disabling automatic simplification like Casio ClassPad
330
(very important to create pedagogical programs that show steps)

2) At least to include missing programming
structures: Dialog-endDlog, Toolbar-endTbar, Custom-endCustm ,
PixelOn, ...
(very important to create advanced programs as Flash Apps)

3) Inclusion of the numeric-graphic ODE solver DIFF EQUATIONS
(very important for finding numerical solutions when DeSolve fail)

4) Inclusion of the numeric-graphic sequence analyzer SEQUENCE
(very important tool to study sequences and recurrences)

5) Advanced 3D graphics (like TI-DERIVE, SPACE TIME, PocketCAS)
http://pocketcas.com/iphone/

6) Full Color on Computer Software, no handheld
http://www.casioeducation.com/prizm/purple

7) TI-89 CAS and PLT-200 CAS emulation software like
http://omnimaga.org/index.php?topic=1301.0

8) High level programing like C (CASIO PB2000), http://www.pisi.com.pl/piotr433/pb2000ee.htm

9) RPN MODE

10) BASIC and C compiler
http://www.midwest-software.com/cBasic/index.html

11) ...

Thanks

[Eric Findlay]

A couple of thoughts/comments:

2) you can create dialog boxes with the Text command. Also, I don't know why you want the commands useful for creating 89 apps when the Nspire doesn't support apps. That's not the purpose of the Nspire.

Also, I'm pretty sure that only reason the other calcs had the Pixel functions is because the algorithm for graphing used a pixelon/pixeloff method, and I'm pretty sure the Nspire graphs differently now, so I don't know that they will/can do that type of individual pixel manipulation. Besides, due to the high resolution of the screen. Turning on one pixel is near useless. Graph or geometry a point instead.

6) Nspire already uses colour in the G&G app on the computer software.

7) is this in addition to the other points? If so, what is the point to emulating the 89 if the other points are also implemented? Also, if you like all the functions and interface of the 89 or other calculator, you should just use that calculator. The Nspire wasn't meant to replace them. And there's only so much space on he calculator. If they load it up with emulations of other calculators that most people don't use, then there won't be much space left for saving document or libraries.

8) have you tried programming on the Nspire? It's very high level. It's basically a scaled back version of C already. What more are you asking for?

I know that I would ask for the ability to initiate errors within a catch block and the ability to define my own error codes.

And, btw, +1 for your suggestions :-)

[Matt Rhodes]

I think you are missing the fundamental purpose for which the Nspire
is made. It is designed to help middle school and high school age
students to better understand different representations of functions
and the relationships that exist between geometric objects - together
with statistics, that's about it. It is, in my opinion the ideal
tool for that purpose for many reasons. It is not, however, intended
to be an advanced programming tool. Have you considered the
different types of PD that is offered through Texas Instruments for
the Nspire - Algebra and Geometry only. Programming isn't even
considered. The current programming tools are offered only as a means
by which teachers can better teach the basics of functions and
geometry. At best, programming on the Nspire is designed to be a
tool, not a basis for curriculum. Rather than upgrades to the Nspire,
it sounds like you need an upgrade to a completely different
calculator.

But, increase the power of the calculator from TI-nspireCAS increases
the $$$ for TI.
TI-nspireCAS can be a calculator universal, secondary and university

[Don Shepherd]

I doubt that it would increase TI's revenues enough to justify the
changes. Hard-core programmers are not going to flock to the NSpire.
Oh, a few will, but I've got to believe that 99% of NSpire sales
represent students, and very few of them are even interested in
programming. The existing programming environment for the NSpire is
sufficient for the few students that use it.

Hello,

Unless we want to turn this thread into a rehash of the long
https://groups.google.com/group/tinspire/browse_thread/thread/2978472efdd30e01
, I think that the two sides are going to have to agree to respectfully
disagree, once again :)

Probably, as there are, indeed, lots of other platforms with better
power / price ratio.

Sadly, that's a fact. And the Nspire's persistently sub-par BASIC isn't
going to help here...
Yes, I'm fully aware that raising (some) young people to being
producers, instead of consumers, isn't quite among the Nspire's goals.

It depends what they're planning on using their calcs for, but you
already know that ;)

For whom were the Finance functions intended?

They usually don't teach about "internal rate of return" in high
school math classes. At least they didn't teach that in mine. :-)

Now that the Ti Nspire has been available for several years, TI should
take stock from their user base as to what new functions they would
like to see.

I agree that programming wasn't the main purpose of the Nspire. But
math was. And there are a number of missing "holes" in the available
math capabilities. For example, you really can't employ statistics
functions that assume a normal distribution until you can assure
yourself that your data is at least approximately normally
distributed. But there are no tests like Kolmogorov-Smirnov on the
Nspire, which can determine if your data approximates some
distribution, such as Gaussian.

There are commercial statistics apps that run on Microsoft Excel. A
comparison of what they offer vs. what the Nspire offers might be
illuminating.

[Andy Kemp]

Hi Steve,

Just for reference many of the Finance tools are used as part of the IB Mathematics Studies courses.

Again, you're missing the point. It is not, nor will it ever be,
intended for those types of purposes. Programming is NOT part of the
curricular intentions for this handheld. Any efforts to make it so
would lead to a lack of vision and focus for the entire project. I,
of course am not speaking for the company officialy, but TI simply
does not have the intentions or manpower to make that happen.

[Mardoxx]

I think the two most important updates would be to enhance the
graphing capabilities of the calculator.
Mainly add functionality for implicit graphing so we can plot
12=x^2+y^2-2xy.
I suppose implicit plot mode could look like this;
f1: y=2*x
f2: 12=y-2*x
f3: x=y^2

Another improvement to graphing would be f(y)= graphs on normal
graphing mode so we can finally plot straight lines and functions of y
without having to convert them to parametric form, which is a pain,

Another, less important, improvement would be polar plotting on polar
grids and complex plotting on the complex plane

Lastly, 3D graphing capabilities... cartesian, spherical, cylindrical
plotting parametric 3d plotting etc... you get the idea


A replacement QWERTY keypad would be a good place for them to make
money [i.e. a separate accessory to replace the current keypad]

Another very important addition would be to be able to plot graphs
with logarithmic scales.

[Nelson Sousa]

I'd also like the ability to reverse the y axis.

Example: one has data for gdp for a set of countries throughout time. We can look at absolute values but as all gdps grow immensely with time it's easier to rank economies to see how's their relative performance, instead of looking at raw data (just immagine comparing gdps for the top economies in the early 20th century with current values).. The problem is that when ranking lower is better and reversing the y axis makes the plot easier to interpret.

Also to plot bouncing ball data collected with cbr2, it's more intuitive o see the chart reversed (instead of flipping the Nspire) ;)

Being able to set ymin > ymax and having as a result a reversed axis instead of an error, that tiny detail could make a huge difference.

Isn't there a way to reverse the y-axis when you set up the experiment using
the CBR 2? I don't have one in front of me right now but I swear I've done
this in the past. Or maybe it was a dream...

Paul

[Nelson Sousa]

No, what you can do is some arithmetic with the lists and plot max(dist)-dist to get the height of the ball instead of the distance to the cbr.

[Mardoxx]

another addition I've since though of is Optional arguments for TI-
Basic
So you can write programs/functions with initial settings but which
can also be changed when calling the function i.e.
mygraph(eqn,x={-10,10},y={0,10})

so you could plot, say y=x^2 from x= -5 to 5 and y= 0 to10 by calling

mygraph(x^2,x={-5,5})

Yep. Right now, you can simulate that effect by passing to the
function a list of all those optional arguments:

{x={-10,10}, y={0,10}}
You can pass that to the function and let it parse it out. Or write a
library to do the parsing separately.

But I admit that's clumsy.


-- Steven L.

[Nelson Sousa]

and if you want to do that on a numeric Nspire you must use strings,
as x={-10,10} will cause an error, as x is undefined. Even clumsier.

Nelson

[Mardoxx]

not really

TI should redesign their programs

== should be is equal to
= should be assign

none of this := rubbish

but just for you, here you go...

[Nelson Sousa]

Sorry, I absolutely must disagree with this one.

1. mathematica also uses the same syntax: = is comparison, := is attribution.

2. from a purely mathematical point of view, = for atribution is just
wrong. An equal sign is a comparison between two entities. The Nspire
is first of all a mathematical learning tool, not a computer
programming learning tool.

3. Plus, that would break compatibility with ALL existing programs for
the TI-Nspire. Not to mention the fact that all of TI's calculators
also use = for comparison.

Nelson

[Eric Findlay]

I'm with Nelson. In addition to all his points, there are several programming languages that use := for attribution, such as ML and all derivatives/variations.

Also, I find it easier to teach high school students programming when there's a larger difference between attribution and comparison. It's easier to spot mistakes in using the wrong operator, both for me and them, and it helps reinforce that there is a difference between the two operators.

[Nelson Sousa]

Ah, the ever lasting debate between educators and programmers...

The TI-Nspire is, first of all, a maths learning tool. An educational platform, aimed primarily at high school and college maths. To learn computer science and/or programming you have dozens of other platorms, much better suited for that end. There are not, however, better platforms or teach and learn maths from.

So, my question is: should the TI-Nspire neglect its main purpose to accomodate the needs and wishes of a community that has developped so little educational content throughout the years or, on the other hand, provide the tools for math educators to develop classroom activities that are much more in number than the small subset of education geared programs of those hundreds you talk about?

Especially when there is, already, a tool much better equiped to answer those needs, in fact two (voyage 2000 and ti-89).

I'm not saying there are no educational tools out there developped by the community. I'm saying there are very few of those, even fewer if you consider true educational content and not just programs, and almost none that allows teachers worldwide to customize, adapt and develop to suit their specific needs.

Just take a look at the activities exchange and see what educational content means.

C is not a good programming language for non-programmers. It's low level, complex and requires too much discipline and general knowledge of the whole language, computer architecture and clock cycles to be useful. Math teachers, for the most part, don't know C, nor have the time, will or skill to learn. They have other skills that are put to much better use developping content easily on the Nspire and teaching maths, instead of spending countless hours in debugging sessions looking at pointers, return values and array indices that may or may not be out of bounds.

I do have some programming skills, though I'm not a programmer, I know very little C and I couldn't possibly develop content in hard core languages. However, my basic programming languages and the fact that the Nspire doesn't require them allowed me to develop quite a few documents where I only care about the underlying maths and the learning process.

Cheers,

Nelson

[Eric Findlay]

Again, interfaces and presentations are not the purpose of the Nspire. The purpose of programs and functions on the Nspire is to reinforce learning, creating and implementing mathematical algorithms. If you want GUI apps, stick with the 89, Voyage or 84.

In fact, TI didn't really want to provide mid-program input, as this is not how mathematical algorithms work, but they finally conceded and put in the text input. Frankly, I don't think they should have, but I digress.

On C, I have to agree with Nelson. As a programmer, I would say that C is much to low-level for non-programmers to be using. Especially since the user would then have access to memory allocation routines, which could lead to corruption the calculator if they're not careful. Like I said earlier, what they have now is like a scaled down version of C++ or Java that includes only the necessary/relevant commands, and combines it with the already optimized commands built into the calculator. However, I would like to make custom error messages and the ability to throw errors.

It would be nice to be able to plot any equation in any form. Heck Microsoft Word can do it.

[Nelson Sousa]

Be caruful of the word "any" (mathematicians hate that word, it carries too many implications and almost never means what one intended). No software (and no human actually) can plot any equation i any form, simply because not all equations can be plotted, soved, etc. Even numerically there are equations so sensitve that slight differences in accuracy render totally different results.

Having said that, implicit 2D and 3D plots are a must, so are differential equations.

Yes, the Graph capabilities definitely need improvement.

Someone else had asked about doing Bode plots on the Nspire. To
display Bode plots that are informative, you need the ability to plot
graphs in logarithmic scale; and with logarithmic scale, you really
need the ability to label intermediate values on the axes: 1, 10,
100, 1000, etc. Right now, the only numeric labels you get are at the
origin and at the ends of the axes.


-- Steven L.

[Nelson Sousa]

That specific feature can be worked around. Add labeled points o the tick marks of the axes and plot log(y) instead of y. It's not ideal but will get the work done.

I have to chuckle at posts like yours on improvements that customers
would like to see TI make. If you understand that the modivation of a
business is to make as much money as possible, and that making product
improvements is costly, then you can understand why TI never comments
on customer suggestions like these. In fact, the only reasons for TI
or any other company to make improvements, is when the competitive
environment causes them to lose a significant amount of sales or
market share, such as when customers refuse to buy more of a product,
or they decide to switch brands, in order to get a certain benefit.
As evidenced by the posts here, that is certainly not the way these
high volume customers think, so until they are willing to change their
purchasing habbits don't count on TI ever making the improvements you
want. Case in point: The new Casio Prizm has a color screen that is
reported to be far better than the nspire screen and I am sure that TI
is watching the situation closely, however if TI doesn't see a
significant decrease in sales of the nspire that can be attributed to
their lack of a color screen, they are not going to decrease their
profit by using a more expensive color screen.

I agree Nelson but do you have any ideas on what can be done to cause
TI to offer implicit 2D and 3D plots and a good differential equation

blind loyality to TI that nullifies the negotiating leverage that they
have in their numbers and volume buying.

Well, Joe, apart from suggesting things, which has been done, and waiting for new features to appear, not much can be done to "force" anything. Repeating the same arguments over a over again, however, doesn't do any good.

As for blind loyalty: show me a better educational tool than the Nspire and I'll switch in the blink of an eye. TI-Nspire may not be perfect but it's by far the best tool available (for my needs, at least).

I think what would "force" TI to add something was a sense that a large number of customers desire that feature. Unfortunately for you, I don't think that is the case for 3-D graphing. May of us, myself included, have no use for that and consequently, are not clamoring to have it added.

Weird, there is nothing wrong with that link for me so...
And its TI-Bank, a very popular website about TI calc, they would
never have porn ads or whatever !

Hi Nelson,
You should check out Mathzone by McGraw-Hill, or the Hawks program, or
WebAssign, etc. Unlike a calculator, these products provide step by
step explanations on how to solve homework problems, as the student
needs that help. Yes, a calculator is valuable for checking ones
answers but there is this huge pedagogical flaw. They don't explain
anything! I would think that providing explanations of how answers
are obtained would be a requirement for a product that is called an
educational tool but obviously TI doesn't see it that way.

We disagree on what can be done to get new features. Nelson, you are
a very knowledgable and determined person, and I am sure that if you
spent as much time convincing teachers not to buy any more TI
calculators with black and white screens as you do programming, we
would very quickly see nspires with color screens for sale.

Yes Lee, you are quite correct and I agree with your logic, except
that it is not unfortunate for me because I switched to superior
alternatives long ago. I have no need for nspire 3-D graphing.
Nspire 3-D graphing alone means nothing. It would be to little to
late. Where is the rest of the stuff that has been missing all these
years?

I hardly spend anytime programming. The Nspire at least. On a side
note, I do quite some programming for a living, but for web
applications.

Judging from the improvements on the OS since the first Nspire's came
out you can't be serious about not being heard by TI. Not you or me in
particular, but the users in general. We've had a lot of what's been
asked for. And yes, I do think 3D graphs and differential equation
graphs will be available eventually. I just disagree with you in that
repeating the same argument over and over again will do any good.
Whoever is listening already heard you. It's like pressing the
elevator button. You may keep pressing it, it won't come any faster
because of it.

And as for explaining the answers, look at the activities being
developped around the world. You'll be surprised. The Nspire allows
teachers to build very good content, aimed at their students and
awesome pedagogical tools. You should take a look at what's possible
with what the Nspire already has, instead of repeating the same
complaints over and over again. Seriously, dude, it gets old! (no
offense, but it does; I suspect you never even looked at what's on
Activities Exchange over at TI's website).

[Rex Boggs]

I think this thread has run its course, so I suggest that anyone who wishes to continue it should do
so off-list. I think the TI folk on the list have by now a good idea about what improvements some
list members would like to see.

Nelson, I understand what you are saying but I am not suggesting that
TI isn't aware of what people want. They know very well what people
want and they are playing hard ball and refusing to provide it or even
discuss it. So if you guys are really serious about wanting a Prizm
like color screen, play hard ball back. Agree among your selves to
not buy any more nspires with black and white screens! That more than
anything else that you can do, will bring about the availability of
the color screen model. But to sit around and wait and hope? Thats
rediculous. It's the most ineffective thing you could possibly do.

BTW I really don't care if TI ever provides a color display. As I
said else where, it would be to little to late. In my opinion they
are so far behind the technology in both hardware and software that I
don't see them ever producing a calculator that I would want.

Sorry Rex, I wasn't aware of your suggestion when I finally finished
and sent my post. No offense intended.

Hi.

Just got off the phone with TI in reference to a problem that has occurred with many, but not all Mac running OS 10.6.4 and 10.6.5: neither version of the Nspire computer software will execute after installation. I received a beta version of a .command file which just deletes some (hidden?) TI files. The fix does work.

TI asked me not to post the file online since it is a beta but rather to encourage anyone to call tech support and ask for it if they need it.

As I remember, this is not the only TI computer software that was in difficulty. I did not ask them, but I would bet that either this routine fixes all of the problems or they have other routines to do so.

PERFECT!!

I've been having the same issues with my TI software as of late. Get
some weird error message and then it crashes. Good to know they may
have a fix...and it's not just me.

And really odd that it is not universal... Mine works fine on 10.6.5. Strange.

This strange, but each version of each computer has it differences. TI Software works fine on both our Macbooks but not my Imac. Way back TI tied it on one of their iMacs and it worked fine. Our school machines seem fine. TI said that there was some subtle change in the Mac OS that caused this. Overall, 10.6.4 has been absolutely stable and compatible for all of our other work.

TI was going to fix my 84 & 30x Smartview issues by logging in
remotely, but these new .command files accomplish the same fix without
having to do the remote log-in. My Smartviews are now working again
(except for 73).

Hi.

Is there a single command to delete all variables in document (assume some are not single letter)?

Thanks,

Al
-------------------------
Albert Coons

[Nelson Sousa]

Short answer: no.
Long answer: still no. :(

And before someone suggests it, it's not feasible to loop through all
possible combinations (we're talking exponential of base 200 or so,
given all the possible chars allowed in variable names, so even with 2
chars there would be... way too many possibilities)

Nelson

[alcoonslists]

Thanks and Ugh. So the best we have is

DelVar var1, var2, var3, ...

Is there formal way to make suggestions to TI for basic changes to the Nspire?

I haven't encountered many situations where I needed to delete a whole bunch of variables. But when I have, what helped was that I had named my variables with consistent names, ie. same prefix and sequential numbers. I could then run a program which looped through all of the variables using indirection.

Marc Garneau

[Nelson Sousa]

well... have you looked at the var menu of the periodic table? At a
given point when we were able to lock variables I decided to lock all
of those. And locking has the same problem as deleting (God forbid I
ever need to unlock them because element 119 is created!).

Nelson

[Wayne Fincher]

I know this is an old thread, but I looked all over for a way to delete all vars on the scratchpad and couldn't find the answer. I have found the answer though. From the scratch pad, press the <DOC> button and then select option <B>. This will clear everything on the scratchpad, including variables.

Hello

SUGGESTIONS TO IMPROVE THE TI NSPIRE CAS OS 2.2 DIC 2010

Many users of TI-89 CAS and PLT-200 CAS are still awaiting for some
of the following capabilities in the TI-NSPIRE CAS:

1)  Enabling or disabling automatic simplification like Casio ClassPad
330
     (very important to create pedagogical programs that show steps)

2)  At least to include missing programming
    structures: Dialog-endDlog, Toolbar-endTbar,  Custom-endCustm ,
PixelOn, ...
    (very important to create advanced programs as Flash Apps)

3) Inclusion of the numeric-graphic ODE solver DIFF EQUATIONS
   (very important for finding numerical solutions when DeSolve fail)

4) Inclusion of the numeric-graphic sequence analyzer SEQUENCE
     (very important tool to study sequences and recurrences)

5) Advanced 3D graphics (like TI-DERIVE, SPACE TIME, PocketCAS)
http://pocketcas.com/iphone/

6) Full Color on Computer Software, no handheld
http://www.casioeducation.com/prizm/purple

7) TI-89 CAS and PLT-200 CAS emulation software like
http://omnimaga.org/index.php?topic=1301.0

8) High level programing like C (CASIO PB2000), http://www.pisi.com.pl/piotr433/pb2000ee.htm
