http://www.freemathvideos.com In this video series I will show you how to simplify trigonometric expressions. We will simplify these expression to either a single trigonometric term or number.  To simplify we will use trigonometric identities such as Pythagorean, reciprocal, quotient, even odd, and co-function.  We will also use algebraic rules to help us simplify the expression such as combining like terms, distributive property, multiplicative, additive inverses, and factoring.
