 Amplitude
The amplitude of a sine or cosine function is a half of the positive difference between the
maximum and minimum values of a function. (Tangent graphs do not have Amplitude)
y=asinbx+c a represents the amplitude

 Period
The period is the length of the
smallest interval that contains
exactly one copy of the repeating
Pattern.
y = asinbx+c , y = acosbx+c
y = atanbx+c
