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 )[1 - sin^2(x)] + sin(x)[1 - 2sin^2(x)], by the Pythagorean Identity. write sin 2x in terms of sin x. Then you could use identity 1. above to get. sin(2x) = 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)).
