Fail. Mod please change that title to *help.

Thank you! How did you get to that Riku? The radical confuses me :(
Manipulate the equation to get:
sin(x) * (2sin(x) + sqrt(2)) = 0
Then you see that sin(x) = 0 is a solution, since it makes the left side of the equation = 0.
Then we need to find values of x that make (2sin(x) + sqrt(2)) = 0, and those values are 5pi/4, 7pi/4.
