**MathMate**, Monday, October 26, 2009 at 11:40amThe same applies as with angles measured in degrees.

Add or subtract 2π until the angle is between 0 and 2π.

1)

Since the angle is negative, we add 2π

-7π/3 + 2π =-π/3

The result is still negative, so we add 2π again to get

-&pi/3 + 2π = 5π/3

Since 0 ≤ 5π/3 ≤ 2π

5π/3 is coterminal with -7π/3.

For 2 and 3, proceed the same way.
