New in v1.1

syntax: xtreema(equation)
You need both fsolve, and xtreema on the calculator, and extreema is not required whatsoever. 
Through arrays, the program extreema, was shortened to xtreema (which is about 4/18 the size of the old program).

The function no longer clears itself (it leaves a lot of junk variables).
It would be a lot better if you used my Advanced Graphing Utility. It allows for so much more, please download and rate. 

----------------------------------------------------------------------------------

syntax: extreema()

This program will find the extreema of a given "y=" (expression)
It is rather simple, but basically, it takes a derivative, solves for x setting the equation to 0, and solves the original expression for one value of x, doing this multiple times to find all the values.

v2.0 will contain the same things, but it will add "point of inflection", "minimum value", and "maximum value".
