A simple and free tools that can make math easy with an advanced calculator.
2.0:
- added vectors; they can be used with normal operators
where appropriate, and can also be used with functions crossP() and dotP().
example usage : crossp([1,2,3],[4,5,6])
- added graphpeq() to draw Parametric equations
- added slpfld() to draw slope fields
- a few bugfixes and optimizations
