Sine and Cosine Periodicity and Phase Shift
Which of the following statements best describes the relationship between the sine and cosine functions with respect to their periodicity and phase shift, as illustrated by the unit circle?
The unit circle demonstrates that sine and cosine functions have different periods, with sine leading cosine by a phase shift of π/4 radians.
The unit circle shows that sine and cosine functions have the same period of 2π, with cosine leading sine by a phase shift of π/2 radians.
The unit circle illustrates that the sine function has a period of π, while the cosine function has a period of 2π, with no phase shift between them.
The unit circle shows that sine and cosine functions have the same period of π, with sine leading cosine by a phase shift of π radians.
