Question

How do you find the amplitude, period and graph `y=sin(4theta)`?

Answer 1

Amplitude= 1
Period= `pi/2`

Explanation:

Amplitude changes when there is a number out in front of sin, so in this case it is 1

Period = `(2pi)/n`
= `pi/2`

To graph,
Sin(4`theta`) must complete 1 wave at `pi/2` so will complete 4 waves in the same distance that sin(`theta`) completes 1 cycle.
