Using the fundemental identities and the Pythagorean Identities, I go over multiple examples of verifying trigonometric identities.
It is very important in proofs that you do not handle it like an equation moving terms and factors from side to side.
I was corrected that what I am trying to prove should not be within the body of the proof. This implies it has already been assumed to be true. So proofs should be shown like this example:
Verifying Trigonometric Identities Part 2
Verifying Trigonometric Identities Part 3
