In this video, we use right triangles to evaluate trigonometric functions with trigonometric ratios, including the acronym SOHCAHTOA. We find the values of the trigonometric functions for 0, 30, 45, 60, and 90 degrees using a 45-45-90 and 30-60-90 special triangles, and see that cofunctions of complementary angles are equal. We also use the definition of trigonometric functions to evaluate at any angle.
