Learn the unit circle with a labeled diagram, and practice problems in both radians and degrees. Perfect for test prep and review.

Using right triangles, we know that every (x, y) point on the unit circle is equivalent to (cos ⁡ θ, sin ⁡ θ). (see previous video) So to find the exact value of tangent at a special angle, we take the x and y …

Jul 8, 2025 · In fact, from the coordinate definition of the trigonometric functions, we should not be surprised to see that, given the point (x, y) on the unit circle on the terminal side of the angle θ, cos …

In the study of circular function s, the unit circle plays a central role in linking angle s with trigonometric values. By defining sine, cosine, and tangent in terms of coordinates on a circle of radius 1, we gain …
