In this video I will show you how to simplify trigonometric expressions by multiplying by the reciprocal, lcd and rationalizing the function. We will do this by first simplifying algebraic complex ...

In this video, I explain how to use Pythagorean identities to simplify trigonometric expressions. We focus on substituting ...

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}} ...
