$\"\"$

The trigonometric function is $\"\"$ .

Make the table of values to find ordered pairs that satisfy the equation.

Choose multiples of $\"\"$ for $\"\"$ and find corresponding values for $\"\"$ .

$\"\"$

Graph :

1. Draw a coordinate plane.

2. Plot the points found in the table.

3. Draw a smooth curve with connecting those plotted points.

Graph of the function $\"\"$ is :

Observe the graph of the function :

There are two complete cycles goes through between $\"\"$ and $\"\"$ .
