APFIVE In what way does the unit circle demonstrate the relationship between the sine and cosine functions, particularly in terms of their periodicity and phase shifts?
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 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 π, with sine leading cosine by a phase shift of π radians.
