I'm currently developing a program that is basically a massive math program. The main thing it does is that it makes it easy for users to add their own formulas/functions into the program and receive special advantages. Functions added into external programs (packages) can be "solved for". For example, a function for growth and decay A=Ce^(kt) can work forwards (finding A given the others) or finding C, k, or t (given A and others). There's a lot to it, and I explain a whole lot in the readme files. But I'm waiting for it to show up on ticalc. Got any faster way?
My hope is that this program will be a good open source engine to tie together all the math programs people have on their calculators into one tidy and effective program.
I've got a bunch of specific questions that I hope you can answer, but I wanted to post this first.
Once I get a link for you all, feel free to start adding your own functions into the program!
