Sin 4x

Sin 4X. We play for a while with the second term 4sinxcosxcos(2x)sin(3x) Note that 2sinxcosx = sin(2x) Using similar reasoning we conclude therefore that 4sinxcosxcos(2x)= 2sin(2x)cos(2x) = sin(4x) A 24 oz box of raisins cost 456A15ozboxof raisinscosts 315 Which is a better deal https//brainlycom/question/7577100.

trigonometry How to simplify $\sin^4 (x)$? Mathematics

$$\sin^4 x = (\sin^2x)^2$$ By using identity $\sin^2 x = 1 \cos^2 x$ we can change $\sin^4 x$ to $$\sin^4 x = (1\cos^2 x)^2$$ $\cos^2 x$ can be changed by using identity $\cos 2x= 2\cos^2 x1$ then $\cos^2 x = \frac{1+\cos 2x}{2}$ So $\sin^4 x = (1\frac12\frac12\cos 2x)^2$20220122.
