The amplitude is 4 and the period is 2π.

Explanation:

Find the amplitude and period of y=4sinθ.

A sine function can be written as y=Asin(BxC)+D

where A is the amplitude

2πB is the period

CB is the phase shift and

D is the vertical shift.

This example, y=4sinθ, may be be written as
y=4sin1θ where
A=4 and B=1

The amplitude is 4 and the period is 2π1=2π.
