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
WebAn angle’s reference angle is the measure of the smallest, positive, acute angle t t formed by the terminal side of the angle t t and the horizontal axis. Thus positive reference angles have terminal sides that lie in the first quadrant and can be … 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.
