Definition of deriative to calculate 4/x^2

Using the definition of deriative (f(x+h)-f(x))/h could anyone show me how to calculate the deriative of 4/x^2? I know the answer is -8/x^3 but I don't know the steps to get there.

Infinite or finite sequence?

What is the sum of the following sequence:
1/1 + 1/3^2 + 1/5^2 + 1/7^2 + 1/9^2 +.....to infinity.
Notice that the sequence is the sum of the reciprocals of squares of ALL odd numbers to infinity. Thanks for any help.
