Review of how to set up a point to evaluate six trigonometric functions

The video tutorial covers evaluating trigonometric functions using the unit circle and triangles. It explains how to find sine, cosine, and tangent for angles on the unit circle and for triangles using the Pythagorean theorem. The tutorial also addresses evaluating trigonometric functions for coordinate points not on the unit circle by creating triangles. The importance of understanding the hypotenuse and its positive value is emphasized. The video concludes with a summary and application of these concepts to homework and tests.
