Hmmmm. YOu must be only in limits,not yet to derivatives.
If there is a function f(x), the derivative is defined as...
lim d>>0 of (f(x+d) -f(x))/d

This is ahead of your class..
http://en.wikipedia.org/wiki/Derivative
One thing I strongly recommend to you, is go visit the nearest college bookstore, or Barnes Noble, and take a close look at this: Schaum's Outline Series, Calculus.
It is inexpensive, chock full of example problems worked, and is easy to read. Don't hesitate...ask mom for an early birthday present of it.
