# Math Help - Determining amplitude and period

1. ## Determining amplitude and period

I know to do this for the sin function but not for the tan function.

How do you find the period and the amplitude of
y=5tan3x

The answer is
period: pi/3
amplitude: not applicable

The amplitude is not applicable because the tan function is unbounded, the period is 1/3-rd the period of tan which is pi radians
