, Period, Amplitude & Frequency
Period (T) interval over which the graph of
function repeats
Amplitude (A) greatest distance of any point
on the graph from a horizontal line which passes
halfway between the maximum & minimum
values of the function
Frequency ( ) no. of repetitions/cycles per unit
of time or 1/T
