Section 5.3 Amplitude , Period and Phaseshift
Shifted sine and cosine curves.
and
- The amplitude is the maximum distance from the midline (horizontal axis) to the peak or trough of the wave.
- The period is the length of one full cycle of the wave (how long it takes to repeat).
- The phase shift is the horizontal shift of the graph (left or right), based on the expression inside the function.
