Using math functions
 

I need to calculate some function using e (the number e). I've been looking around and I can't figure out how to use it. I looked in math.h and didn't see anything useful. Also how do you correctly code exponents without just doing x*x*x*x.....? Thanks!

Just found the pow() function for the exponents.. still trying to figure out how to use e though.

look at exp() for e^x

I'm not sure what you mean by "the number e", but for exponents, pow(3,2) is equivalent to 3^2.

EDIT: Make sure that pow() uses arguments that are double or float type, they both must be the same type. It's return value is also a double or float type.

If you are going to display the output of pow(), make sure you use the %f specifier (if you are coding in C).
