3 sin^2 T - sin T = 1/4 ????
let z = sin T
3 z - z = 1/4
z - z/3 = 1/12
z - z/3 + 1/36 = 3 /36 + 1/36 = 4/36 = 1/9
(z-1/6)^2 = 1/9
z = 1/6 +/- 1/3
z = 1/2 or z = -1/6
if sin T = 1/2
T = 30 degrees or pi/6
if sin T = -1/6
T = -9.6 degrees
let z = sin T
3 z - z = 1/4
z - z/3 = 1/12
z - z/3 + 1/36 = 3 /36 + 1/36 = 4/36 = 1/9
(z-1/6)^2 = 1/9
z = 1/6 +/- 1/3
z = 1/2 or z = -1/6
