This applet is designed for the exploration of approximation of functions by Taylor polynomials. The graph shows the function and the chosen approximation. It also give numeric values for the function and the approximation at a chosen point. A choice item lets the user control whether a mouse click on the graph centers the graph at that point, moves the base point X0, or moves the approximating point X1. When a point can be moved by clicking, it can also be moved by dragging.

The source. is well documented, but all the files have been put into a single text file, so you will need to rename the file and separate into classes before compiling.
