The integral is .
Graph the integrand function .
Shade the required region.
\Observe the graph :
\Region enclosed by the given curve is between and
.
Area between the curves and
and between
and
is
.
Here integration is considered with respect to axis, hence
.
Observe the graph:
\The integrand function is negative in the interval and positive in
.
Area of the region , .
.
Area of the region is sq-units.
Area of the region is sq-units.
