Question 942007:
(sin^4x-2sin^2x+1)cosx=cos^5x
I have to verify the identity.I know I have to try and prove one side or the other. so I started out trying to solve the left side. I multiplied it all by cosx but that seemed to complicate things. Answer by richard1234(7193) (Show Source):
You can put this solution on YOUR website! Identity is pretty simple to verify; however you have to notice that . Using , we have , so the LHS equals .
