Learning Center
The Amazing Unit Circle The unit circle definitions of the trigonometric functions provide a wealth of information about those functions.
Exact Values of the Trigonometric Functions at the "nice" angles. All the values collected on one page.
Exact Values of Inverse Trigonometric Functions at the "nice" values. The values of inverse sine, inverse cosine and inverse tangent collected on one page.
More facts will be added, so be sure to come back and visit again soon.
- Common Trigonometry Mistakes Real mistakes from real student work
Now available: Amazing Unit Circle t-shirt shows properties of the trigonometric functions that are easily observed from the unit circle definitions of these functions. It's a great gift for students and teachers.
