Secant and Tangent lines

This is a simple applet to show the relationship between the secant and tangent lines, and to help the student understand how the secant line approximates the tangent line under a limit. (The word limit is not mentioned in the applet). Students can change the function to see how the secant line behaves in different contexts.
