Trig Function: Anything left I havent gotten to yet...

[nalathethird]

I am going to add any remaining Trig functions and anything else that would be popularly used for calculating in input fields.

Mainly going to try to add the rest of commonly known trig functions and then possibly add a few others like Factorial and possibly exponents depending on how hard that will be to make.
otherwise, this should wrap up the actual FEATURE SET for the mod unless we have popular demand to add anything else.
