Passing Parameters that control or modify behavior of applet is truly an innovative and interactive way to program. If an applet uses variables to control speed, names of music files (au), names of image files (.jpg), color, or postition or whatever, you, the programmer, can modify those variables by passing their values thru the HTML that runs the applet! This allows a "robust" and "user-friendly" applet. This state-of-the-art feature has become a standard for applet programming!

100 points. for typing this in and clean compile.
100 comment each line thoroughly in your words.
100 for adding (2) other Math methods (sq root and 1 other). Think -- you know the code for this!
100 for posting this on your web site.
