This is known as the Gaussian integral, after its usage in the Gaussian distribution, and it is well known to have no closed form. However, the improper integral. I = \int_0^\infty e^ {- x^2} \, dx I = ∫ 0∞ e−x2 dx. may be evaluated precisely, using an integration trick. In fact, its value is given by the polar integral.

2 Answers Sorted by: 1 If your heart's set on a solution using Feynman's trick, note ∫∞ 0re − ar2dr = 1 2a ∫∞ 0r3e − ar2dr = 1 2a2. So − I(a)I′(a) = ∫R2x2e − ar2dxdy = ∫2π 0 cos2θdθ∫∞ 0r3e − ar2dr = π 2a2.
The Feynman integration trick and Leibniz rule epitomized with three examples YouTube
However, as we will see, utilizing Feynman's path-integral formulation of quantum mechanics, Gaussian integrals are also central for computation in quantum statistical mechanics and more generally in quantum field theory. A. one degree of freedom Let us start out slowly with standard, scalar, one-dimension Gaussian integrals Z 0(a) = Z ∞.
Solving the Gaussian Integral using the Feynman Integration method by Rthvik Raviprakash Medium
On its last page, the author, Mr. Anonymous, left several exercises without any hints, one of them is to evaluate the Gaussian integral ∫∞ 0 e−x2 dx = π−−√ 2 ∫ 0 ∞ e − x 2 d x = π 2 using this parametrization trick. I had been evaluating it through trial and error using different paramatrizations, but no luck so far.
Variant Gaussian Integral e^(a x^2)cos(b x), from 0 to infinity, General Case, Feynman's trick
The trick of inverting Feynman's trick by integrating the integral of interest to make a double integral and then reversing the order of integration is introduced. The Cauchy-Schlӧmilch transformation is stated, derived, and used to evaluate some interesting variations of the probability integral. Download chapter PDF 3.1 Leibniz's Formula
Visual proof of Feynman's Trick Leibniz Integral rule YouTube
Among a few other integral tricks and techniques, Feynman's trick was a strong reason that made me love evaluating integrals, and although the technique itself goes back to Leibniz being commonly known as the Leibniz integral rule, it was Richard Feynman who popularized it, which is why it is also referred to as Feynman's trick.

The double integrals are surface integrals over the surface Σ, and the line integral is over the bounding curve ∂Σ. Higher dimensions. The Leibniz integral rule can be extended to multidimensional integrals. In two and three dimensions, this rule is better known from the field of fluid dynamics as the Reynolds transport theorem:
