# Secant to Tangent Applet

This applet is designed to build the student's visual intuition about the line tangent to a curve at a point being the limit of the secant lines through that point. There are pre-coded examples and the user may also input functions. In addition, the user may control the graph window settings. The user controls the parameter $$\Delta x$$ and the point on the graph.
