How do you find the reference angle
WebFinding the reference angle If necessary, first "unwind" the angle: Keep subtracting 360 from it until it is lies between 0 and 360°. (For negative angles add 360 instead). Sketch the … WebExample 2: Find the reference to angle A = - 15 π / 4. Solution to example 2: The given angle is not positive and less than 2π. We can use the positive and less than 2π coterminal A c to angle A. A c = - 15 π / 4 + 2 (2 π) = π / 4 Angle A and A c are coterminal and have the same reference angle. A c is in quadrant I, therefore A r = A c = π / 4
