TI-nSpire Navigator problem
weki
get to work. I contacted TI and they could not figure out the problem
so sent me a new access point but this did not fix the problem. I am
running XP Pro SP3. I am able to connect to the access point with two
different computers. I received the second access point last Thursday
but TI had shut down for the Holidays by the time that I found it did
not correct the problem.
On the TI-nSpire holding down the ctrl key and typing WWW will bring
up a diagnostic screen. Here is what I get:

The person at TI was concerned that nothing appeared after the first
AP:. What concerns me is that there is no MAC Address or Cradle ID.
It received the new style cradles that have a slide switch that says
ON or OFF when locking the cradle to the handheld.
Can anyone offer any ideas?

displayed on the TI site and indicates that the TI-nspires must be in
TI-84 mode.
TI-Navigator system is compatible with the following TI graphing
calculators:
• TI-73 Explorer™
• TI-83 Plus
• TI-84 Plus
• TI-84 Plus Silver Edition
• TI-Nspire™ technology when used in TI-84 mode. Additional
applications will need to be downloaded to use the two together.

The information mentioned above, is meant for the (old) TI Navigator
system, not for the (new) *TI-Nspire* Navigator system. The new
system should work with the TI-Nspires in TI-Nspire mode.

I hope you find resolution soon. Let us know (or the Nspire Nav group) what solves the issue.
Thanks,

Thanks. This solved the problem. I loaded the OS from the Navigator
disk and things worked.
I had been running OS 1.7.2741 2009-05-19
Installed OS from disk 1.7.1 Build 50
There seems to be a numbering problem with the OS.

I was wondering about that too. I had the same experience Weki. I
thought the OS on my handhelds was more current due to the numbering.
I finally loaded the OS on the CD to a unit and then everything worked
fine.
Is the only change with OS 1.71 functionality with Nspire Navigator?

I like 1.7.1 OS on the Nspire with the TI-Nspire Navigator. Right, the only change is in Nspire Nav functionality.
I'm sure that will be part of the trick for the next OS update, is getting everything to work with each other. I doubt that they would want to continue having a special OS for Nspire Nav users. I wouldn't expect the next OS until around T^3 International in Atlanta. Then some people will opt to keep using what they know until the end of the school year, or for AP teachers, they may wait until after the AP exam. When it does come out I'll let you know why I would update before the Calc exam or wait a month or so because students are used to what they have. (Knowing me, I'll probably update as soon as I can and tell you what the students think. We'll let you know what things are better, especially for the calc students.)
Hope you are having a great break.

future I will be skeptical of any information that I read on the TI
web site. As you can see, there is no mention of an old or a new TI
Navigator system in the information that I obtained from the TI site
and provided in my posting here.
MESSAGE TO TI: In an attempt to be of assistance to one of your
customers I offered information that you publish on your web site.
Unfortunately, based on the corrective information offered below, what
I provided from your web site was misleading. I believe that you (TI)
have a moral obligation to provide clear and accurate up to date
information for products that you provide, when you make them
available. Please take appropriate corrective action. Thank
you.

Probably also a good idea for all of us to be skeptical of anything
Joe posts here.
Joe
In an attempt to be helpful (which I didn't have to do), I went to the
TI site at www.ti.com.
Then I did a search on that home page for the generic term
"navigator."
That returned about 25 links.
One link is for a TI-nspire navigator interest form.
5 links are for TI-nspire navigator Texas instruments events for US
and Canada.
None of the remaining links mention TI-nspire navigator, nor TI-nspire
navigator features, nor
TI-nspire navigator technical information.
The only link that provided any technical information at all was a
features summary for TI-navigator which I quoted in my post.
Nothing was returned from the TI search engine that suggested that
there was a separate nspire version of the navigator so perhaps TI
will take corrective action to fix that.
Since I am not a mind reader I had no way of knowing, from the
information returned by the TI search engine, on the TI site, that a
separate nspire navigator exists. Again, perhaps TI will correct that
missleading situation.
As for your suggestion that "probably also a good idea for all of us
to be skeptical of anything Joe posts here." Based on what has
happened, that is certainly a reasonable suggestion. Thank you.

(like calculators and such) - remember that TI is a major manufacturer
of integrated circuits and processors that are totally unrelated to
education, the educational part is only a small portion of TI's
business - and I hovered over "Products"; there I found an item (at
the bottom of the menu) called "TI-Navigator systems" - note the
plural. I clicked there and to my surprise I find two items listed:
"TI-Nspire™ Navigator™ System" and "TI-Navigator™". On the first one
there's info about Navigator for Nspire and Nspire CAS, the second one
doesn't mention any calculators but has pictures of the 84 Plus Silver
Edition and 83 Plus and has a huge button saying "View compatible
graphing calculators".
I don't think it's reasonable to say that the information about the
two different Navigator systems is hidden behind some awkward site
navigation - pun not intended - architecture. It's right there, under
products - one coule even say under your nose.

ask you a question. This is something I have been wondering about and
perhaps you have the answer. ( I am using the nspire cas software but
the same thing should occur using the nspire cas handheld.) When I
enter 1/sqrt(7) where sqrt is actually the square root sign from the
keypad, then when I press enter, the auto simplify routine returns sqrt
(7)/7 as expected. It has automatically rationalized the
denominator. But when I enter 1/sqrt(7x) and press enter, in this
case the sqrt(7)/7sqrt(x) is returned where the sqrt of 7 in the
denominator has been rationalized but the square root of x has not.
Why is that? Also, when I try to force the rationalization by
entering 1/sqrt(x) * sqrt(x)/sqrt(x) the program returns 1/sqrt(x) and
I can't find a way to force the rationalization of sqrt(x) in the
denominator. The solution would be a "rationalize" command. How
else can one cause the program to rationalize the sqrt(x) in the
denominator? It's also interesting that the auto simplify routine
won't rationalize things like 1/(sqrt(x)+1) but it will rationalize 1/
(sqrt(7)+1). Weird huh?

rationalizing the denominator when x is unknown may not result in the
most simplified answer when the x is all of a sudden known.
In example of 1/sqrt(x), you get a result of 1/sqrt(x) and expect
sqrt(x)/x. If you have x=3, then the expected result would be the
nicest (sqrt(3)/3), whereas, if x=4, then the result given would be
nicest (1/2). Now, I know that really, for x=4, they both simplify to
the same thing, but I would guess that the way it was programmed was to
wait until all variables are known, then simplify in the most efficient
way possible.
I also know that this isn't ideal, as the students can't use the
calculator to rationalize expressions with variables (or is that a good
thing?), but you could take it as a teaching moment.
As for "forcing" it to rationalize, I would say that it's because the
calculator simplifies each term first, so your 1/sqrt(x) *
sqrt(x)/sqrt(x) is really 1/sqrt(x) * 1.
For I am convinced that neither death nor life, neither angels nor
demons, neither the present nor the future, nor any powers, neither
height nor depth, nor anything else in all creation, will be able to
separate us from the love of God that is in Christ Jesus our Lord.

if it could, though.

does it rationalize properly if you use | and set the variable?
ie: 1/sqrt(x) | x=7 or 1/sqrt(x) | x=9

equal to another variable name. For example it rationalizes 1/sqrt(x)
| x=7 but won't rationalize 1/sqrt(x) | x=y. I suggested a
rationalize commmand in another post because it if sometimes important
in higher math. (See my post on the thread on rationalizing.) That
is not to say that students need to rationalize every answer, but it
is important to continue teaching the concept. Thanks for the help.

installed that OS to all of my handhelds (including the ones owned by
my students) the next day. We had no problem associating the cradles
to the system and have been using them everyday this week. Good luck!

new Navigators all week in all classes. I was able to get everyone
connected each day. We are having fun. Occasionally it takes some
switching of cradles or waiting or turning off and off units but we
did it. It is fantastic. I can hardly wait to see how far we can go
with it.
