The unit circle defines trigonometric functions in right triangle relationships, specifically known as sine, cosine, and tangent. © HowStuffWorks 2021 You probably have an intuitive idea of what a circle is: the shape of a basketball hoop, a wheel or a quarter. You may even remember from ...
A "unit" circle has a radius of 1. In other words, the distance from the center of the circle to any part of the edge is always 1. The unit of measurement doesn't really matter, because the most important thing about the unit circle is that it makes many equations and calculations ...
Unit circle can be used to calculate the values of basic trigonometric functions-sine, cosine, and tangent. The following diagram shows how trigonometric ratios sine and cosine can be represented in aunit circle. Trigonometry Identities In Trigonometric Identities, an equation is called an identity ...

The trigonometric functions are most simply defined using the unit circle. Let be an angle measured counterclockwise from the x-axis along an arc of the circle. Then is the horizontal coordinate of the arc endpoint, and is the vertical component. The ratio is defined as . As a result of ...
