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 5.2. 6. Figure 5.2. 6. Using our definitions of cosine and sine, x = cos t = cos ( 90 °) = 0 y = sin t = sin ( 90 °) = 1. WebSine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. ... Look at the left-most figure above (the unit circle). The triangle's hypotenuse has length 1, and so (conveniently!) the ratio of its adjacent to its hypotenuse is cos(θ), and the ratio of its opposite to the hypotenuse is sin(θ). ...
