Abstract

 In this article, first, with a simple technique, we obtain a wellknown formula about the gamma function and some theorems of Laplace transforms. After that, we mention a new formula, which can be used to calculate some not so convenient improper integrals, and also with the help of it and the Gaussian integral, we obtain a new convergence result regarding Hermite polynomials. Then with the help of the same formula, we obtain a new model for the gamma function in natural numbers.
