To get the reference angle, convert the angle measurement to degrees first since it is in radians.
The conversion factor is pi = 180°
So,
Since 315° is located in quadrant IV, to get the reference angle, subtract 315° from 360°. Hence, the reference angle is 45°.
Based on the basics of trigonometric functions, Tan (45) = 1.
