Unit Circle - Math is Fun
The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here.

7.3: Unit Circle - Mathematics LibreTexts
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 7.3.2. The angle (in radians) that t intercepts forms an arc of length s. Using the formula s = rt, and knowing that r = 1, we see that for a unit circle, s = t.
