Step 1:
\The function is
.
Find the area between function and
-axis on the interval
.
Area of the region between two curves:
\The area of the region biunded by the graphs of
and
and the vertical lines
and
is
.
Graph the functions
and
on 

Observe the graph:
\The intersection point of two functions is
.
on the interval
.
on the interval
.
The area of the region is
.
Substitute
and
.





.
Area between the
-axis and
is
.
Solution:
\Area between the
-axis and
is
.
