If cos 4 A cos 2 B + sin 4 A sin 2 B = 1, then sin 4 A + sin 4 B = 2 sin 2 A sin 2 B. Well, I thought to start it this way: ( sin 2 α − cos 2 α) ( sin 2 α + cos 2 α) = 2 sin 2 α − 1 => ( sin α − cos α) ( sin α + cos α) ( sin 2 α + cos 2 α) = 2 sin 2 α − 1. 1. Prove the following identity. Prove the identity sin 4 α − cos 4 α = 2 sin 2 α − 1. Limits.
