WebIn mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.In topology, it is often denoted as S 1 because it is a one-dimensional unit n-sphere..

Find WebExample 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. bold and the beautiful april 26 2019
