Abstract

Numerous examples where various types of de nite integrals evaluated
using a technique exploiting exponential generating functions are presented.
We show how some classically famous but tricky integrals can be readily found
using such an approach. Brief historical remarks on some of the more notable
integrals considered are made. Application of some of the integrals found to a
class of classically important series containing the central binomial coecients
are given.
