Question

2sin^2 (x)=sinx
solve the equation for exact solutions over the interval [0,2pi)

Answer 1

Re-writing your equation like this may make it easier for y ou and for others to decipher (understand):\[2\sin^2 (x)=sinx \rightarrow 2(\sin x)^2=\sin x\]

First, think about how you would solve the following: 2c^2=c. Hint: subtract c from both sides, and then factor the resulting equation.

Answer 2

Well, I was wondering, I know my answer is 0 and pi but, do you think it could be any other factors?
