Evaluate the composition of trigonometric functions by creating a right triangle. In this video we will evaluate the tangent by given the ratio for cosine. To do this we will use right triangle and ...

Note: This only works when \(x\) is measured in radians. We are now going to look at more complex trigonometric functions where we will use the general rule: \(\int {\cos (ax + b)dx = \frac{1}{a}} ...
