What is theta if "2sin-squared-theta=1"? (between 0 and 360). I know that theta is 45 degrees, but what else is it (135? 225?)

 

[Foxodi]

2sin^2 x = 1 0<x<360
sin^2 x = 1/2
sin x = +or-1 / root of 2

Positive or Negative, therefore all quadrants

Q1 = 45
Q2 = 135
Q3 = 225
Q4 = 315

Therefore x = 45, 135, 225, 315
