Question

What is the amplitude, period and the phase shift of `y=2sin3x`?

Answer 1

For a function of the type

`y=A*sin(B*x+C)+D`

The amplitude is `A`
The period is `2*pi/B`
The phase shift is `-C/B`

The vertical shift is `D`

Hence in our case the amplitude is `2` , the period is `2*pi/3` and the phase shift is `0`
