Answer:
Define a periodic function:
A periodic function is a function that repeats its values at regular intervals. For example, the trigonometric functions, which repeat at intervals o radians, are periodic functions.
Take for instance a sine function below
Step 2:
Define the amplitude of a function:
The amplitude of a function is the amount by which the graph of the function travels above and below its midline. When graphing a sine function, the value of the amplitude is equivalent to the value of the coefficient of the sine.
Step 3:
Define the period of a function:
The Period goes from one peak to the next (or from any point to the next matching point):
This is the time it takes complete one cycle
From the equation of a sine function,
The period is represented below as
TAKE FOR EXAMPLE ,
The sine equation given below
The graph will be given below as
