How to use unit circle trigonometry
Did you know?
In 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 because it is a one-dimensional unit n-sphere. If (x, y) is a point on the unit circle's circumference, then x and y are the lengths of the legs of a right …
WebThe unit circle is the circle whose center is at the origin and whose radius is one. The circumfrence of the unit circle is 2Π. An arc of the unit circle has the same length as the measure of the central angle that intercepts that arc. Also, because the radius of the unit circle is one, the trigonometric functions sine and cosine have special ...
