amplitude 
aAmplitude 

Amplitude 

a stretch, with stretch factor 2 in y-direction

The amplitude  of %5Csin%20x%20 is 1

The amplitude  of a%5Ctimes%20%5Csin%20x%20 is a%5Ctimes%201


Period 

a stretch, with stretch factor 1/2 in x-direction


The period of %5Csin%20x%20 is  2%5Cpi%20

The period of  %5Csin%20(ax%20) is %5Cfrac%7B1%7D%7Ba%7D%20%5Ctimes%202%5Cpi%20
