Solve over [0,360): sin^2 theta = cos^2 theta + 1
sin^2 theta - cos^2 theta - 1 = 0
sin^2 theta - cos^2 theta - sin^2 theta - cos^2 theta = 0
2cos^2 = 0
theta = 90 degs, 270 degs

Solve over [0,360):
sin^2 theta = cos^2 theta + 1
-----
sin^2 = 1-sin^2) + 1
---------
2sin^2 = 2
sin^2 = 1
sin = +1 or sin = -1
theta = 90 degrees or theta = 270 degrees
