Key Concepts

Amplitude

Amplitude refers to the maximum displacement of a periodic function from its midline. In the context of trigonometric functions like sine or cosine, it is the absolute value of the coefficient that multiplies the sine or cosine, indicating how 'tall' or 'deep' the waves are relative to the center line of the graph.

Period

The period of a trigonometric function is the horizontal length required for the function to complete one full cycle. It is calculated by taking the standard period of the sine or cosine function (which is 2?) and dividing it by the absolute value of the coefficient of the variable inside the function's argument.

Phase Shift

Phase shift represents the horizontal translation of a trigonometric function along the x-axis. It shows how much the graph has shifted left or right from its standard position. This shift is determined by factoring the expression inside the sine or cosine function and identifying the constant term that causes the translation.

Graphing Sinusoidal Functions

Graphing a sinusoidal function involves plotting one complete cycle of the wave by marking key features such as the midline, amplitude, period, and phase shift. These key features help in sketching the curve accurately, capturing its starting point, maximum and minimum values, and periodic nature.
