Any Sin function can only vary
between and
----------------------------
times a sin function varies from
to
---------------------
varies between
and , so the amplitude is

Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the amplitude of the function is 3.

here's a graph of the function without adding the pi at the end so you can see the amplitude better.

here's the same graph after putting the pi back in.
you can see that the graph has shifted up pi units.
the amplitude is still 3 however.

here's a link to a tutorial on the sinusoidal wave.
