A Simple Derivative Grapher
|
|
|
In this tutorial, the user enters an arbitrary function and clicks a button to display its graph.
Then the user can sketch the derivative of the function on the graphing board using the mouse.
Clicking another button reveals the actual graph of the derivative. The applet uses the classes
provided in our article "Flash Tools for Developers: Function Grapher" and one of the
function grapher templates
from that article. Through simple modification of the code,
we change the functionality of the template to make displaying
the graph of the derivative possible. We also show how to easily change
the appearance of the grapher. In this tutorial, we illustrate some of the many methods of the custom GraphingBoard class.
For the complete description see the PDF guide in the above mentioned article.
