Key Concepts

Trigonometric Ratios

Trigonometric ratios, including sine, cosine, and tangent, are defined in terms of the coordinates of a point on the terminal side of an angle. In the context of the unit circle, the sine of an angle is the y-coordinate, the cosine is the x-coordinate, and the tangent is the ratio of the sine to the cosine, provided the cosine is not zero.

Unit Circle

The unit circle is a circle centered at the origin with a radius of one unit. It is a fundamental tool in trigonometry that provides a geometric representation of the sine and cosine functions, with any point on the circle representing the coordinates (cos?, sin?) for an angle ?.

Angle in Standard Position

An angle in standard position is defined with its vertex at the origin of the coordinate plane and its initial side on the positive x-axis. This standardization allows for a consistent method of measuring and analyzing angles regardless of their orientation in the plane.

Terminal Side

The terminal side of an angle is the ray that emerges from the vertex after the angle has been drawn from the initial side. It represents the end position of the angle and is crucial in determining the coordinates or points that relate to the angle, such as those found on the unit circle.

Reference Angle

A reference angle is the acute angle formed between the terminal side of a given angle and the x-axis. It simplifies the computation of trigonometric functions by relating any angle to an acute angle, which has well-known trigonometric values.
