This applets lets you try to construct a graph of the derivative [br]of a random function. Raise or lower the points to indicate the [br]derivative of the function at that point.

The checkboxes will let you:[br][list][br][*] Connect the points of the constructed derivative with a smooth curve [br][*] Show tangent segments on the original curve from the proposed derivative[br][*] Show the graph of the actual derivative.[br][/list][br]A button lets you choose a new random function.[br]the accuracy reading goes up to 100.[br]This applet is based on one produced by Marc Renault.
