There are two important types of integrals: definite and indefinite. The definition of a definite integral is that it has limits of integration. An indefinite integral does not have limits of integration. The gamma formula is a definite integral. The gamma function is also an improper integral....

. Stirling's approximation is asymptotically equal to the factorial function for large values of n. It is possible to find a general formula for factorials using tools such as integrals and limits from calculus. A good solution to this is the gamma function. There are infinitely many continuous...

A number of integrals that yield to Euler's development of the gamma function integral generalization of the factorial function are center-stage in this chapter. The historically important Wallis integral is the starting point, which quickly leads to the beta function and the discovery by Euler of...
