Quadrant Analysis

The quadrant in which the terminal side of an angle lies affects the signs of its trigonometric functions. By determining the quadrant using the signs of the x and y coordinates, one can properly assign positive or negative signs to the computed function values.

Coordinate Geometry and the Distance Formula

When a point lies on the terminal side of an angle in standard position, its Cartesian coordinates (x, y) are used to define the sine and cosine of the angle. The distance formula, given by r = ?(x² + y²), calculates the distance from the origin to the point, which serves as the hypotenuse in the associated right triangle.

Standard Position of an Angle

An angle is said to be in standard position when its vertex is at the origin of the coordinate plane and its initial side lies along the positive x-axis. This positioning allows for a consistent method to determine the trigonometric function values by considering where the terminal side intersects the coordinate system.

Trigonometric Functions

These are the six functions—sine, cosine, tangent, cosecant, secant, and cotangent—that relate angles to ratios of sides in a right triangle or points on the coordinate plane. They form the basis of trigonometry and are defined using either triangles or the unit circle, providing a critical link between geometry and algebra.
