Insert a geogebra application allowing the user to use a slider to shift the phase of a periodic function.
Manipulative 1: Phase shift.

A phase shift is a horizontal shift for a periodic function. If a periodic function is shifted a multiple of one full period, so that it is identical to the first function, it is said to be in phase. If a periodic function is shifted by an amount not a multiple of one full period, it is said to be out of phase.
