Project: Maths Solver

Hi,
I have to develop maths tutor for my final year project. (The maths area is calculus). The tutor will include, calculator feature which solves the usual calculus problems (i.e intgral, differential, trig function, draw graphs of functions etc)

(The calculus is based on undergrad levels)

I don't have a clue where to start to do research and where to investigate the algorithms that are used in other similar maths tutor applications out there. (e.g Mathematica, Maple etc)

I would be grateful if you know any sites/books that contains information relevant to my project.

Check out FORTRAN.

Thank you for replying.
I should have said in my thread that I am only going to use Java for my project. I don't know what FORTRAN is, but i guess it's a programming language right?

And, I think I should have been more specific in my first post. What I am currently stuck in is how to program the system to recognise what user type in. More specifically, I think what I want is a parser.
E.g when user types in say, Integrate[3x^2], -2x^3 + 3x^3 - 6, etc the program should recongise that it has to integrate the function 3x^2 and recongise that -2x^3 + 3x^3 - 6 is polynomial and can be simplified to 1x^3 - 6.

I would be very grateful if anyone could help me or know good sites that have this information.

-Merry xmas & Happy New Year to all

if this is going to be in java i don't know. there is free source code for xcas here:

it is C++

for a parser, if you are in linux, you can look at bison.

thanks. but this is not what i'm looking for. I don't use linux.

Yeah. Formula Translator, it hails from the days way back when Java was either an Indonesian Island or a slang term for Coffee, but not a programming language ...

But it's not extinct!
