Derivatives are an application of limits. The animation illustrates the convregence of secant lines to the tangent line at a point. The slope of the tangent line is the derivative of the function at this point.

The six lessons in this unit are organized to first develop a
Conceptual Understanding of the Derivative and Precise Definition of the Derivative. A collection of Differentiation Rules are stated - and proven - for algebraic and Trigonometric Functions. These rules make it possible for us to use derivatives without having to apply the definition every time. The most powerful differentiation rule --- the Chain Rule --- is considered separately. Implicit Differentiation provides a technique for finding the slope of the tangent line to a curve even when the curve is not the graph of a function.
