In this paper, the Euler-Maclaurin formula is exploited to provide an expression for the q-factorial function as an infinite integral.

The Dirichlet test for convergence of infinite integral shows that

Since the infinite integral in the previous theorem is convergent, then we have

The evaluation of these infinite integrals when all the terms are written out in full form become very unwidely and moreover we have to perform the inverse Laplace transform to these expressions in order to find the temperature and stresses in space time domain.

Simultaneous calculations for the inversion of double Fourier transforms were done by evaluating the infinite integrals (2.

However, the essence of his material is virtually timeless, covering real variables, functions of real variables, complex numbers, limits of functions for a positive integer variable, limits of functions of a continuous variable, derivatives and integrals, theorems in the differential and integral calculus, the convergence of infinite series and

infinite integrals, the functions of real variables (logarithmic, exponential and circular) and their real functions.
