+130511 The sine is equal to 1/2 at 30 degrees and at 150 degrees on the interval 0 to 360 degrees, inclusive.
A more general form is: 30 +n360 and 150 + n360 ... where n is an integer.
In radians, it would be pi/6 and 5*pi/6 with the general form being:
pi/6 + n(2pi) and 5pi/6 + n(2pi) ... where n is an integer.
