The four compass points of the unit circle chart (N, S, E, W) are the angles that have coordinates of 0 and 1 or -1, and they're special because you can't draw a reference angle triangle for them: you've just got to use the unit circle. Sine and cosine aren't too bad for these, but for tangent and the reciprocal functions you've got to choose. The Unit Circle is a circle with a radius of 1. The angle that we rotate the radius uses the greek letter θ.

The tangent of an angle is the ratio of the y-value to the x-value of the corresponding point on the unit circle. Because the y-value is equal to the sine of t, and the x-value is equal to the cosine of t, the tangent of angle t can also be defined as sint/cost, cost≠0 OUTPUT on the unit circle is the value of 1, the lowest value of OUTPUT is -1. Range of Sine and Cosine: [- 1 , 1] Since the real line can wrap around the unit circle an infinite number of times, we can extend the domain values of t outside the interval [,02 π]. As the line wraps around further, certain points will overlap on the sam In mathematics, a unit circle is a circle with a radius of one.
