Question 736851: Use a power reducing identity to rewrite the following expression below in terms containing only first powers of cosine. cos^2(x)sin^4(x) Please help me to understand this in the simplest way possible. Answer by fcabanski(1391) (Show Source): You can put this solution on YOUR website! cos^2(x) = (1+cos(2x))/2 and sin^2(x) = (1-cos(2x))/2. sin^4(x) = (sin^2(x))^2
