I'm using the up carrot sign to signal "to the power of..."

Let sin theta = x

x - 2 x^2 = 0

x (1 - 2x) = 0

Both x=0 and x = 1/2 are solutions.

theta = 0 degrees, 30 degrees, 150 degrees and 180 degrees.

Thank you so much!!! im a little confused on how you got the degrees though. I know that is what you are supposed to end up with but i cant connect how you go from the solution to the degrees. could you please explain?

if x= sintheta=0

then theta= arc sin 0

On your calculator, this may be the inv sin or sin

oh right! thank you so much!
