Help with basics and finite difference method

I have to write a program using the finite-difference formula to calculate the approximate value for the derivative of a function. The test will be tan(x) for x=1, determining the error by comparing with sec^2(x). I have no idea where to begin.

How about a for loop and taking the delta Y over the delta X where the separation is decreasing until it gets really really small, then compare to sec^2(x) and see how the difference gets smaller and smaller as the separation gets smaller and smaller. That's the finite difference method.
