${\displaystyle \underset{a}{\overset{\phantom{}}{}}}f(x)dx+{\displaystyle \underset{b}{\overset{\phantom{}}{}}}g(x)dx$

where $a=,b=,c=$ and

$f(x)=$

$g(x)=$

Alternatively this area can be computed as a single integral

${\displaystyle \underset{}{\overset{}{}}}h(y)dy$

$$

where $=,=$ and

$h(y)=$

Either way we find that the area is
