WebJan 21, 2024 · The unit circle is the circle of radius 1 that is centered at the origin, ( 0, 0). If we pick any point ( x, y) that lies on the unit circle, the point is associated with a right triangle whose horizontal leg has length x and whose vertical leg has length y , as seen in Figure 2.2. 1 By the Pythagorean Theorem, it follows that. WebFor instance, there's a lot to learn from the similar and right triangles in the figure I call the "Complete Triangle"; also, the "Law of Cosines" (for acute triangles, anyway); even the power series representations of at least four of the six trig functions.
