Feynman's Integration Trick YouTube
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.

POWERFUL Integration Technique!! Feynman's Trick Ideas and Examples Gaussian Integral YouTube
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

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 ∞.

∫e⁻²ˣ²cos(3x) dx [∞,∞]. Solving Integration by Feynman’s Trick with extension of Gaussian
The integral is easily evaluated: F (t) = 1 t for all t > 0. Differentiating F with respect to t leads to the identity: Taking further derivatives yields: Which immediately implies the formula: The right hand side is the famous Gamma function, and does not depend on n being an integer.

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:
