If someone could point me in the right direction of where to go with these sorts of problems, I would be so greatful :p

Solve the equation for x, where 0</x<2pi

2 sin x + 1 = 0

Solve the equation for x, where 0</x<2pi

2 sin x + 1 = 0

Hey everyone, I hope this is in the right spot...For some odd reason this was never covered in my book so I'm not quite sure what to do with it.
