We can use the unit circle to help define the trigonometric functions and visualize their values.Solution. 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 = cost = cos(90°) = 0 y = sint = sin(90°) = 1.

Then look at the coordinates of the point where the line and the circle intersect. The first coordinate, i.e. the \(x\)-coordinate, is the cosine of that angle and the second coordinate, i.e. the \(y\)-coordinate, is the sine of that angle. We’ve put some of the standard angles along with the coordinates of their intersections on the unit circle.

35. It seems evident from infinitely many primitive pythagorean triples (a, b, c) ( a, b, c) that there are infinitely many rational points (a c, b c) ( a c, b c) on the unit circle. But how would one go about, and show that they are dense, in the sense that for two rational points x x and y y of angles α α and β β on the unit circle, if α ...

A unit circle has a center at (0, 0) and radius 1. The length of the intercepted arc is equal to the radian measure of the central angle t. Let (x, y) be the endpoint on the unit circle of an arc of arc length s. The (x, y) coordinates of this point can be described as functions of the angle.
