Hello! I'm taking an advanced chemistry course and an equation solver for the ti-nspire would be a great help. It would need to include ideal gas law equation solver, van der wall's adjustment equation solver, partial pressure solver, collision equation solver, thermodynamic equation solver, chemical balancer (with redox), mole solver, and basically anything you think would be helpful to a chemistry student possibly looking into majoring in chemistry, all of them being able to solve for any variable. Thank you for your time, and any help is greatlly appreciated. Sorry if this is a double post, i don't think my last one about this posted.

Aww... That's a bit disappointing that i'll not be able to at least use it on my final, but thank you very much! My teacher actually just told me today that he has an nspire, except without the touchpad. He said that his nspire is able to run ti-84 program files and stores the ones he's not using on it as well. There are a few 84 programs that i've seen for chemistry, any idea if i would be able to both load and run 84 programs on my nspire? I just updated it to OS 3.2. And i have another question. If you don't mind answering it as well.
We are supposed to make what he's calling a 'mini-cartoon' using matrices to create a picture and run it through animations by creating a program for it to translate, rotate, and change the image's size. I'm planning on creating a cutscene-type thing of Young Link from OoT going into the Temple of Time and drawing the Master Sword. I have the matrix for the sword and it in the pedestal, but i have no idea how to make it move and switch between the images. I have a lot of time to do it, but i'm trying to get a head start on it by at least learning how i'll be able to make it move with matrices once i have everything planned out in more detail. Any ideas?

oops. i knew i updated to the most current, i didn't pay much attention to it. and i have no idea how to even program in basic, so i'm fine with trying to learn Lua if it means i'll be able to do the project. i know nothing about basic, anyways and i enjoy a challenge. any tips or tricks? oh, and thank you very much for everything, my friend.

Sorry for the extremely late answer! (skipped the topic)

http://inspired-lua.org contains Lua information (and tutorials) for the nspire.
General Lua info (since Lua works on other platforms too) is just a google away

And about 3D, do you mean the math side? In that case, not really

No problem, glad I could help
Don't be afraid to ask if you got any problems

I have written a chem app that solves Gas Laws. You can find it on my site here: http://www.mason-cole.com/#TI-Nspire
