These videos explain how to:
1. Sketch and use graphs of the sine, cosine and tangent functions (for angles of any size, and using either degrees or radians)
2. Use the exact values of the sine, cosine and tangent of 30°, 45°, 60°, and related angles
3. Use the notations sin-1 x, cos-1 x, tan-1x to denote the principal values of the inverse trigonometric relations
4. Find all the solutions of simple trigonometrical equations lying in a specified interval (general forms of solution are not included).
5.
