Today, I am going to be talking about verifying identities. This is a very complex topic, as it is basically proving the identities in various situations of trigonometric functions. There are a bunch of tips and rules. First, you can only work on one side of the graph. Two, it is suggested that you pick the more complicated side, although when checking your work, you could use the other side. Another tip is to remember the algebra tricks such as grouping and multiplying by the conjugate. When you've mastered all of these tips and tricks, you will be able to verify!
Thanks,
Kaili Chiu
