public class FunctionComposition
A Function composation applet displays the graphs of two functions, f(x) and g(x), and their coposition, g(f(x)). It marks points (x,f(x)), (f(x),g(f(x)), and (x,g(f(x))) on the respective graphs. The user controls the value of x by dragging a red square along the x-axis of the first graph. The functions f and g can be given as table functions instead of expressions. The user controls this by clicking on check boxes. When a table function is displayed, the user can modify it by dragging its points. Optionally, the apple can also display tangent lines to the graphs. The slopes of the tangent line are supposed to illustrate the chain rule. Note: This inherits from GenericGraphApplet, but a lot of code in that applet is superceded here. In particular, there is no possibility of having a limit control panel.
