GonioLab UC visualizes the 6 trigonometric functions as well as the 6 hyperbolic functions.
- The Trigonometric functions are; Sinus, Cosine, Tangent, Cosecant, Secant and Cotangent.
Common abbreviations are; sin, cos, tan, csc, sec and cot. - The Hyperbolic functions are; Hyperbolic sinus, Hyperbolic cosine, Hyperbolic tangent, Hyperbolic cosecant, Hyperbolic secant and Hyperbolic cotangent.
Common abbreviations are; sinh, cosh, tanh, csch, sech and coth.
Read about the Unit circle, the Trigonometric functions and the Hyperbolic functions at Wikipedia.

application did not start after dowloading
Im sorry to hear that. What Java version do you have and what is your operating system?
GonioLab requires Java 6.
I have java 6 under XP
Your other applications run correctly
I tried on a XP machine here and it started ok. You could try again, after you cleared the java cache with the following command: javaws -uninstall
It works fine now
Thanks for your answers
That’s good news.
Crashs when displaying trigonometric functions for phi = -pi, under Mac OS 10.6.2 with up to date Java.
Thanks for reporting it. Could you try to isolate which of the functions causes the crash? You can begin with selecting all but csc and see if it works ok, and then select only csc.
Hello. Tried the Unit Circle java app. Excellent work. Did not crash at all (Win 7 with IE 9.0 and JavaRTE 6.x). Only lines for white background may be too thin for example to project in a classroom screen with either white or black background. Nevertheless, very good work. I am not a java programmer but trying to use the Unit Circle to figure the inverse functions should be next challenge. Two questions: 1) How can we port the Gonio Lab Unit Circle to Android, 2) Can I have your permission to show capture images on my research paper on new coherent ways to teach trigonometry enhanced with technology? Please reply to my email.
