+130514 I'm assuming you want to find an angle with the same value as -cos(300)
cos(300) = 1/2 ....so ...-cos(300) = -1/2
So, you're looking for an angle with a cosine value of -1/2
This occurs at 120 degrees and at 240 degrees
The general answers would be
120 + n360 and 240 + n360 where n is an integer
