$\"\"$

The amplitude of the sinusoidal function is $\"\"$ .

The period of the function is $\"\"$ .

To sketch the graph, divide the interval of one period $\"\"$ into required intervals of same width.

Scale the $\"\"$ -axis using $\"\"$ interval as the basic unit.

Adjust the scale on the $\"\"$ -axis to accommodate the amplitude $\"\"$ .
