$2\sin 2^{x}=\sin x$ are you sure it looks like that?

2. marasofia1616 Group Title

$2 \sin ^{2}x=\sin x$

sorry this is how it looks like

pi / 4 = 45 5pi / 4 = 135

2 sin^2 x = sin x 2 sin x = 1 dividing both sides by sin x sin x = 1 / 2 dividing both sides by 2 arcsin (1/2) = x so x = pi/4, 5pi/4
