$\"\"$

The functions are $\"\"$ and $\"\"$ .

Graph :

(1) Draw the coordinate plane.

(2) Graph the functions $\"\"$ and $\"\"$ on the same graph.

$\"\"$

Observe the graph :

Both the curves intersect at the points $\"\"$ and $\"\"$ .

Since $\"\"$ for $\"\"$ and $\"\"$ for $\"\"$ .

The area of the region is $\"\"$ .

$\"\"$

$\"\"$ and $\"\"$ are the odd functions,so the region bounded by the curves is symmetric about the origin.

The area of the region is $\"\"$ .
