The Unit Circle

Unit Circle is a Circle whose radius is 1. The center of unit circle is at origin0,0 on the axis. The circumference of Unit Circle is 2 units, whereas area of Unit Circle is units 2. It carries all the properties of Circle. Unit Circle has the equation x 2 y 2 1. This Unit Circle helps in defining various Trigonometric concepts.

A unit circle is a circle of radius 1, often used in trigonometry and complex analysis. Learn how to define and use the unit circle, its trigonometric functions, and its applications in mathematics and physics.

A unit circle is formed with its center at the point0, 0, which is the origin of the coordinate axes. and a radius of 1 unit. Hence the equation of the unit circle is x - 0 2 y - 0 2 1 2. This is simplified to obtain the equation of a unit circle. Equation of a Unit Circle x 2 y 2 1
