The Command is described in page 123 (129 using the PDF page) of the nspire CAS manual. If you can do that symbol on the blue nspire i don't see why it wouldn't work, but this calc seems to be an enigma in that it actually seems to do less than their previous models. I can almost see Ti removing the command to use the extra memory for the ti-83 emultion or just to sell CAS's. Why they would do that is beyond me.

thanks, but here is the thing, apparently the templates dont work because when I try to use them it says that they only work for the CAS. But when i try to derivate the other way by nDeriv( the way the guide tells me to it says "Error: Variable is not defined". I really don't get this calculator. If the CAS doesn't integrate then I'll just have to use the TI-84 plus keypad that it brings. I still think it wasn't a good Idea to make a calculator that doesnt integrate.

Ohh, I forgot to mention that i just bought the Nspire because i lost my TI-89 titanium. I bought it because when I looked up calculators i thought that the TI-Nspire would be just like the TI-89 Titanium but with a better GUI.

You would think the Nspire would be better, but it seems gimped to me from what I can tell.  It's more of a portable PowerPoint presenter and a data collector than it is a graphing calculator.

I swear that Ti anymore builds their calcs based on high school teacher input instead of Math professors and scientist input. Teachers want pretty graphics and ease of use while professors and scientists want raw power and calculation expandability. Teachers don't want programming capabilities because in their mind it turns them into a gameboy (Completely ignoring the fact that programming takes math to make a game work right not to mention gets students interested in computer programming) while professors want programming to solve complex problems without having to enter 20 equations manually each time. I think this is the same reason the Ti-82 OS keeps living on and on and the Ti-85 OS is dead, even though the Ti-85 OS was much more superior in many aspects and ran on basically the same hardware with a slightly bigger screen. The Ti-92 is the last calc OS they made with Both Teachers and Professors in mind. Thankfully they haven't snuffed it like they did the Ti-85/6 yet but who knows, they'll probably replace it with the Ti-84 super saiyan edition anytime now with bright flashing yellow case, 16 MB of flash and the same limitations and 24K Ram Footprint the Ti-82 has had for almost 15 years now.

Anyway, Have you tried updating the OS on it? It sounds like they added some program functionality to it, but still not enough to make it programmable. Maybe they added some more commands as well.

where can i update the OS?

I'm kind of mad because why would they make 2 different Nspire with almost no difference between them:S

It makes me feel like the one i bought is obsolete
