Chapter 6.1, Problem 51ES

Suppose that $f$ and g are continuous on $\left[a,b\right]$ but that the graphs of $y=f\left(x\right)$ and $y=g\left(x\right)$ cross several times. Describe a step-by-step procedure for determining the area bounded by the graphs of $y=f\left(x\right),y=g\left(x\right),x=a,$ and $x=b$ .
