Moving 90° counterclockwise around the unit circle from the positive x axis brings us to the top of the circle, where the (x, y) coordinates are (0, 1), as shown in figure 2.2.6. using our definitions of cosine and sine, x = cost = cos(90°) = 0 y = sint = sin(90°) = 1. the cosine of 90° is 0; the sine of 90° is 1. Finding function values for the sine and cosine. to define our trigonometric functions, we begin by drawing a unit circle, a circle centered at the origin with radius 1, as shown in figure 2. the angle (in radians) that t t intercepts forms an arc of length s. s. Sine and cosine graphs. in the graph of the sine function, the x x axis represents values of \theta θ and the y y axis represents values of \sin \theta sinθ. for example, \sin 0=0, sin0 = 0, implying that the point (0,0) (0,0) is a point on the sine graph. if we plot the values of the sine function for a large number of angles \theta θ, we.
