Recursion has more expressive power than iterative looping constructs. I say this because a while loop is equivalent to a tail recursive function and recursive functions need not be tail recursive.

This Java recursion tutorial shows you how to create a recursive Java factorial function and compares these methods to iterative ones.

I am have a slight problem with two recursive functions I wrote: Sine and Cosine. Each function depends on the other (and itself) to compute the value of Sine and Cosine for any value input. I am ...
