Find all solutions if 0 degrees is less than or equal to x and x is less than 360 degrees.
2 sin^2(x)+ sin(x)=1
treat it like a quadratic.
Some students like to change it using something like this:
let sin(x) = y , then
2y^2 + y - 1 = 0
this one factors nicely, once you found y, sub that back into sinx
