How do you find the reference angle
WebThis time, we are going to find the reference angle of a negative angle: -23 degree. Same as the last example, we draw the standard angle of -23 degree on a xy plane. Also, starting from the x axis (zero), however, this time we turn the terminal arm to the negative direction. At the end, we know that the standard angle = -23 degree. 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
