1. To verify a trig identity simply means to show how one equation can be manipulated and simplified to equal the other equation. You can't touch the right side of the equation because that is already the simplification of the 1st. equation. When you verify it, it justifies whether the answer would be correct or not.
2. The tips that I really found helpful were the factoring out. GCF is another one that is really helpful to me. Also multiplying by the conjugate and separating of the fraction. GCF more since i tend to have been using it the most. And I cant really explain why or how but it is the easiest one in my head to do.
3. My thought process when verifying a trig identity is 1st. are there any identities here that can be changed or replaced to be simpler. Then, can and should i change into sin and cos? see if there is anything that i can do to cancel and get the minimum amount of trig functions. If they are fractions, then try to get a GCF. I might also separate some fractions. Afterwards i will simplify by using algebra.
