Question

2 ((sin^2)x) = sin x

Answer 1

subtract sin(x) both sides, what do you get?

Answer 2

2 ((sin^2)x) - sin x = 0

Answer 3

But how would I factor?

Answer 4

pull out the common factor

Answer 5

\[2\sin^2x-\sin x=0,\sin x \left( 2\sin x-1 \right)=0\]
either sinx=0
x=?
or \[\sin x=\frac{ 1 }{ 2 },find x\]

Answer 6

Regarding your "2 ((sin^2)x) = sin x" ... I think you probably mean 2 (sin x)^2 = sin x Think about this. What's your conclusion?

If you agree with my interpretation, you'll then have \[2 (\sin x)^2=\sin x, \]

Answer 7

or \[2 \sin^2x=\sin x\]

Answer 8

How would you solve that for x?
