Sure, the area, $\displaystyle \displaystyle A$ between two curves $\displaystyle \displaystyle f(x)$ and $\displaystyle \displaystyle g(x)$ on an interval $\displaystyle [a,b]$ is given by $\displaystyle \displaystyle A = \int_a^b [f(x) - g(x)]~dx$
provided $\displaystyle \displaystyle f(x)$ is always the top function on the interval $\displaystyle \displaystyle [a,b]$
