- Derivatives using the limit definition 

 

- Definition of the Derivate: You choose the function and two points on the function, this applet will graph the secant line between the two points and calculate its slope. It should also make it clear why a limit is needed to find the slope of the tangent line.

 - The Derivate Function: The (blue) derivative of the (red) function is equal to the slope of the (green) tangent line. Hopefully this point-and-click applet helps you to visualize the relationship.
