Inclined Plane

Methods responding to Boolean Variable states.

This has sound. You will need your sound volume turned up in order to hear it.

small angle approximations

Move your mouse near the vertex of the angle, the green segment and the blue segment. The angle, the Sine of that angle, and the Tangent of that angle are close in value if the angle is small. This leads to some convenient substitutions.

Yo 2.0!

This computes an average GPA required over new courses a student would have to earn in order to meet a 2.0 GPA minimum requirement to graduate.

3D Graphics

This program needs work. It does not yet represent realistic perspectives based on up/down and left/right displacements from the object. Please comment on my oversight if you can. Press space bar to render initial view. Adjust slider values and press space bar to render new view.

3D Perspective

Green Flag runs Intro. Space Bar advances Intro. "z" exits Intro. Move eye with arrow keys. Rotate eye with "a" and "d" keys. Change Field of View (FOV) with "w" and "s" keys. Changing FOV acts as a zoom function.

SQRT Newton's Method Recursive Loop Form

This is a modification of a project by BATzerk. (Hopefully this will be useful in the future when I need it to calculate the magnitude of speed.) It's a very simple program, but I hope it will come in handy to those Scratch users who are frustrated because they can't figure out how to get Scratch to give them a square root function! =) Thanks BATzerk!
