    Should be 0, 5pi/4, 7pi/4.

    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.
