Example 2: Use the unit circle with tangent to compute the values of: a) tan 495° b) tan 900°. Solution: When the angle is beyond 360°, then we find its coterminal angle by adding or subtracting multiples of 360° to get the angle to be within 0° and 360°. a) The co-terminal angle of 495° = 495° - 360° = 135°. tan 495° = tan 135° = -1.The unit circle formula has been explained here along with a solved example question.
