Graphing Trigonometric Functions
Graphing trigonometric functions involves plotting the sine, cosine, and tangent functions on a coordinate plane. Each function has a unique shape characterized by its amplitude, period, and phase shift. Understanding these properties is essential for accurately determining the equation that represents a given graph.

Introduction to Trigonometric Functions
Amplitude and Period
Amplitude refers to the maximum height of a wave from its midline, while the period is the distance over which the function completes one full cycle. For sine and cosine functions, the standard amplitude is 1, and the period is 2π. Adjustments to these values in the function's equation affect the graph's appearance, making it crucial to identify them when determining the equation.

Phase Shift
Phase shift describes the horizontal displacement of a trigonometric graph from its standard position. It occurs when the function is modified by adding or subtracting a constant inside the function's argument. Recognizing the phase shift is vital for accurately writing the equation that corresponds to the graph, as it indicates how the graph is shifted left or right.
