To see how to handle the problem of an unbounded integrand, we start with the following special cases.

Cases where has an infinite discontinuity only at an interior
point **c, a <c < b** are handled by writing

and using the definitions to see if the integrals on the right-hand
side exist. If *both* exist then the integral on the left-hand
side exists. If *either* of the integrals on the right-hand side
diverges, then does not exist.
