Step 1:
\The curve equations are
and
.
Definite integral as area of the region:
\If
is continuous and non-negative on the closed interval
,
then the area of the region bounded by the graph
, the
-axis and the vertical lines
and
is given by
.
Observe the graph:
\The point of intersection of the graph are
and
.
Upper curve is
.
Lower curve is
.
The area of the region bounded by the graph
, the
-axis and the vertical lines
and
is


Solution:
\
