**cos 2x = 2 sin x Math Central**

10/09/2010 · -( cos^2(2x) - sin^2(2x) ) -cos(4x) There other ways we could have simplified it, but the important thing here is that we got everything down to one term, so that's as simplified as it gets.... How do you solve #sin^2x-1=0# and find all exact general solutions?

**1-Sin / 1+Sin 2000clicks.com**

Substitute u back into the equation to get 1/4*(2x - sin(2x)) + c. Simplify to get x/2 - (sin(x))/4 + c. Tip For a definite integral, eliminate the constant in the answer and evaluate the answer over the interval specified in the problem....The equation `sin^2x=1/4` has to be solved for x. `sin^2x=1/4` `sin x = +- sqrt(1/4)` `sin x = +- 1/2` Now to determine x, take the arc-sine of both the sides
