This program enables the user to define functions
of one variable and then do various operations on the functions.
Once the function f is defined then the program will evaluate
f at a point or a range of points. The program also differentiates
f at a particular point and will evaluate the definite integral
using Simpson's rule. Mathtool will also solve the equation f(x)=0
and will then let you graph up to five functions at the same time.
