Properties of the Unit Circle

The unit circle has several important properties that make it a useful tool for solving problems in mathematics and other fields. Some of the key properties of the unit circle include: * The radius of the unit circle is 1 unit. * The center of the unit circle is at the origin (0, 0) of the coordinate plane. * The unit circle is symmetric about the x-axis and the y-axis. * The unit circle has a circumference of 2π units. * The unit circle has an area of π square units.

Trigonometric Functions

The unit circle is used to define the trigonometric functions, such as sine, cosine, and tangent. These functions are defined as the ratios of the lengths of the sides of a right triangle with a hypotenuse of 1 unit. The sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. The cosine of an angle is defined as the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
