You probably know that when the function entry line is showing you can click the two upward pointing chevrons on the right to reveal many of the functions - but not 40 :).  Screen shots could be easily gathered.
On the blog post http://bird-godlydominion.blogspot.com/2009/01/graphing-picture.html I recommend having the students write down the functions, polar equations, etc. to turn in. The short video gives a demonstration of a file a student made.

I sent the students a starter file called "aPic" when the objective and a blank Graphs & Geometry page. Then a day or so latter I could collect the file with the Nspire Navigator. That made it easy to have a record of what they did.
Besides pre-calculus, are there other classes that you would do this activity with?

Have a great day.

As you are planning on printing them - the best thing would be to transfer them to the computer then open them in the software version - in 'normal' view you can display 10 equations at a go...

40 equations? Wow!

One possibility is adding labels to the graphs (the label of a graph
is the equation), but at most you can have 3 or 4 on screen at the
same time. Otherwise it would be quite confusing. You can display all
of them, but I don't think you'd like the result.

I used to do this on graph paper with trig students (before calculators!) and also with precalc.  The students love this and I find they learn more about functions, domain, and range than they ever did with my carefully planned board lessons.  My students(precalc honors) have been working on their projects for the last 4 or 5 classes and have created some very cool designs.

Another display idea:
When students are done they could insert a Calculator page or a Notes page and press var to recall all the defined functions.
On the Calculator page after pressing var and selecting the function, then they press x and enter to display the function. Repeat for all the functions. Then like Andy recommended, if you view this on the software you can view many of these at the same time.
If you use the Notes page you can evaluate the function or polar equation, e.g. r1(theta), using the right-click shortcut ctrl menu > Evaluate.

I agree this is a valuable exercise, and even more so on the TI-Nspire then on previous handhelds.

Only problem with this is that you cannot evaluate f1(x) etc if you are not using the CAS handhelds...  Which is a shame!

Good call. Thanks, I often live in my CAS world and forget about limitations like that.
Quite right.
I do like my Calculator/Notes page idea more than the spreadsheet because of pretty print, but only for the TI-Nspire CAS.

I agree, if you have CAS this is neatest solution!

It would be nice if there was a simple way to just recall the definition of a function on the numerical handheld...

This is one of my favorite activities! I have done this activity for
the past two years after seeing Tom Reardon's presentaion a few years
back. My students generally spend between 3 and 6 hours on the
project outside of class over a period of two weeks. I also do like
Sean and send a file called "graph picture" using the TI-Nspire
Navigator so I can easily collect the file. The class monitors each
other's progress by using the Screen capture tool of the TI-Nspire
Navigator at the end of class every couple of ddays so the class can
see how everyone is doing. We then do a class vote using a quick pole
and pass out the prize for each hour. Please see the files "Graph
family picture winners 2009" and "graph family e-mail to staff."

You could use my polynomial toolkit to do this quite easily.

Get the file "poly.tns" from the Google site and drop it into MyLib.
Then

1. In a Calculator page, run poly\pvar("x")

This lets you enter functions without the need for "quotes".

2. Just run poly\xpress(f1(x)), then poly\xpress(f2(x)), etc

As long as your functions are polynomials they will be nicely
displayed.

That would be nice but their functions are all in parametric form.

Easy: just run poly\pvar("t")

Then poly\xpress(x1(t)) and poly\xpress(y1(t)) etc
