[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 S1 because it is a one-dimensional unit n -sphere. The sine of t is equal to the y -coordinate of point P: sin t = y. The cosine of t is equal to the x -coordinate of point P: cos t = x. Example 13.2.1: Finding Function Values for Sine and Cosine. Point P is a point on the unit circle corresponding to an angle of t, as shown in Figure 13.2.4. Find cos(t) and sin(t).
