Key Concepts

Terminal Side and Standard Position

This concept involves the position of an angle in the coordinate plane, where the initial side lies along the positive x-axis and the terminal side passes through a given point. Understanding this setup is essential because it connects the angle to specific coordinates in the plane, which in turn are used to determine the trigonometric function values.

Right Triangle and Pythagorean Theorem

When a point lies on the terminal side of an angle in standard position, one can visualize a right triangle formed by dropping a perpendicular from the point to the x-axis. The Pythagorean theorem is used to find the hypotenuse (or radius) of this triangle, which is critical for calculating sine, cosine, and other trigonometric functions.

Trigonometric Function Definitions

Trigonometric functions are defined based on the ratios of the sides of the right triangle associated with an angle. Specifically, sine is the ratio of the opposite side to the hypotenuse, cosine is the ratio of the adjacent side to the hypotenuse, and tangent is the ratio of the opposite side to the adjacent side. The reciprocal functions (cosecant, secant, and cotangent) are defined accordingly. These definitions enable the exact calculation of the six trigonometric functions when the coordinates are known.
