Learn how to use the unit circle formula to find the coordinates of any point on the circle in terms of sine and cosine. See examples, practice problems, and interactive graphs of sine, cosine, and tangent. The Unit Circle The point of the unit circle is that it makes other parts of the mathematics easier and neater.

For instance, in the unit circle, for any angle θ, the trig values for sine and cosine are clearly nothing more than sin(θ) = y and cos(θ) = x. Working from this, you can take the fact that the tangent is defined as being tan(θ) = y/x, and then substitute for x and y to easily. In mathematics, a unit circle is a circle of unit radius -that is, a radius of 1.

[1] Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
