Bank of america loan modifications , Us bank closing equity lines , and You can put this solution on YOUR website! cos 2x - **sin x** cos(2x)=1-2 sin^2 x.
Therefore we have 1-2sin^2x-**sinx**. That is -(2sin^2 x+**sin x**-1)=-(2sin x-1)(**sin x**+1)
. Not clear if that answers the question or whether both **sin x and cos x** have to be
present. cos (2x)=2 cos^2 x -1. Then it is 2 cos^2x -**sin x**-1 . (1) First, find sin(3x) and **cos(3x**) in terms of sine and cosine as follows: sin(3x) =
sin(2x + x) = sin(2x)**cos(x**) + cos(2x)**sin(x**), by the sine addition formula = 2sin(x)
cos^2(x) + **sin(x**)[1 - 2sin^2(x)], by the sine/cosine double-angle formulas = 2sin(x

**sin(x**)**cos(x**) + **cos(x**)**sin(x**) = 2 **sin(x**)**cos(x**). This is not quite correct since I have
cos(2x) in terms of **sin(x) and cos(x**). But identity 2. above says that. **cos(x**) = sqrt(
1 - sin2(x)). where sqrt is the square root. Thus. sin(2x) = 2 **sin(x**) sqrt(1-sin2(x)). **only** work on the leﬁ side of the equal sign, but this is not the **only** veriﬁcation
