Example 3 Find the six trigonometric functions of the angle C=1020 degrees. Solution Note that the clockwise angle 1020 degrees equals 1020(/180) = 17/3 radians. This angle equals two complete revolutions of 4 radians plus the angle 5/3 = - /3 radians an angle in the fourth quadrant. From the triangle in the above diagram we see that:
