This is one of the most common examples of the need for recursive functions. Recursive functions, at their simplest, are functions that call themselves. These types of functions are used in the ...

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 ...
