You might be interested in
The most generic sine function you can write is
Of all these constant, affects the amplitude,
affects the wave length,
and
cause horizontal/vertical translation.
In your case,
And we are interested in the amplitude, so we focus on
The amplitude of the standard sine function is 1, so when you multiply by , the new amplitude is
itself. In our case
, so the amplitude is 4.
