I have a few questions on how to evaluate some mathematic stuff in Obj-C.

1st - How would I evaluate the square root of a number?

2nd - How would I evaluate logarithms?

3rd - I'd assume the way to deal with exponents would be using a carrot (^)?


Thanks in advance for any help provided.

Are these actual mathematical questions (i.e how to do it) or programming questions (how to implement it)?

Look into the following functions:

pow()
log()
sqrt()

should give you everything you need.
