Well, this is my first blog for the holidays. Maybe i shouldn’t have waited so long to do it, but oh well. Okay, i can’t do a blog about the last few thing we learned because i forgot my binder at school. But i will do it on the things i can remember; finding coterminal angles.

When in radians you either add or subtract two pi, depending whether or not they want a positive or negative angle. If they want a negative angle, subtract 2 pi. If they want a positive angle, add 2 pi.

Example 1: find a positive coterminal angle for pi / 2.
pi / 2 +2pi = 5pi / 2

When in degrees you either add or subtract 360 degrees. If they ask for a positive coterminal angle, then you add 360 degrees. If they want a negative coterminal angle, you subtract 360 degrees.

Example 2: find a negative coterminal angle for 32 degrees.
32 degrees – 360 degrees = -328 degrees.

Well, thats pretty much it.
