$\"\"$

The trigonometric function is $\"\"$ .

Write the function $\"\"$ as the sum of the two functions form is $\"\"$ .

Consider the functions as $\"\"$ and $\"\"$ . \ \

Draw a coordinate plane.

Graphs the functions $\"\"$ and $\"\"$ in the same coordinate plane on the interval $\"\"$ . \ \

$\"graph$

The graph of $\"\"$ is obtained by adding each value of $\"\"$ in $\"\"$ and the corresponding value of $\"\"$ in $\"\"$ . \ \

If $\"\"$ , then $\"\"$ will be above $\"\"$ by a distance equal to $\"\"$ .

If $\"\"$ , then $\"\"$ will be below $\"\"$ by a distance equal to the absolute value of $\"\"$ .

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