The task is to find the shaded area above between the two curves
and
which intersect at the points
I labelled the curves top and bottom. Using this sophisticated notation, the area is
Sometimes it is not quite so obvious what the equation of either the top or bottom curve is.
The graph is
We have to find the area of the region marked A. The top is obviously
W take as bottom the curve
then
are the solutions to
so
OR
so
so
We have then
