The derivative of a function is the limit of the slope of the secant line between two points as the distance between the two points approaches 0 and the Instantaneous Rate of Change at a point.

If the derivative has the same domain as the function, the function is differentiable or has a derivative on that domain.

A function may not be differentiable if there is a corner, cusp, or vertical tangent. Also, the function is not differentiable if it is a step function.

Limit Definition of the Derivative

Here are the major rules that you will use to take the derivative of any function.

Here are some derivatives that need to be memorized before the AP exam.
