Question
Need help identifying on the right.

Transcribed Image Text:Verify that the following equation is an identity.
cos 3t = cos t-4 sin t cost
To verify the identity, start with the left side and transform it to look like the right side. Choose the correct transformation and transform the expression at each step.
cos 3t = cos (2t +t)
= cos 2t cost- sin 2t sint
(1-2 sin t) cos t- (2 sin t cos t) sin t
2,
= cos t-2 sin t cos t-2 sin t cos t
= cos t- 4 sin't cos t
