What is this? This Java applet demonstrates is the relative lengths of the 6 trigonometric functions. Angle A (black line) is a central angle on the unit circle (radius: 1 unit), bouncing from 0° to 90° in increments of 1°. The values of the six trig functions are represented by the lengths of the colored lines, and their decimal approximations are displayed in the list above. Future plans for this include:

Sohcahtoa Applet: Release
1.03 for JDK 1.0x |

- NEWS -
3/10/99 - Version 1.03: On Screen
Conrols
This new version adds the beginings of on-screen controls. Now you can start
and stop the animation, manually change the value of theta, as well as set the unit
circle size (meaning size relative to the screen, aka zoom, not the RADIUS of the
unit circle, which is of course, always 1).
2/17/99 - Version 1.02: Better
Colors
The colors and weight of the lines have been changed, hopefully making them easier
to see. The jdk 1.1.x version will be put on hold until more browsers support
the 1.1 specification.
2/4/99 - Version 1.01: Theta Workaround
The applet has been upgraded (or downgraded, rather) to work with the older (but
more widely used) jdk1.0.x specifications, and as such, the angles are now simply
referenced as "A." The jdk1.1.x version is here
if you'd like to check it out.
