Amplitude: The amplitude in the equation determines the maximum displacement from the midline.

Frequency: The frequency in the equation determines how many cycles are completed in one unit of time.

Phase Shift: The phase shift in the equation represents a horizontal translation of the graph, indicating where it starts on the x-axis.
