Insights A Novel Technique of Calculating Unit Hypercube Integrals

Click For Summary
The article presents a novel technique for evaluating unit hypercube integrals, beginning with a theorem on Dirichlet integrals. It introduces a sequence of nested sets that converge point-wise to a unit hypercube, integrating these concepts using the Dominated Convergence Theorem. The technique aims to provide a systematic approach to integration, enhancing understanding of Dirichlet integrals, which are linked to Gamma functions. Additionally, the article references an expanded insight piece that explores fractional integral representations of special functions. The discussion culminates with the completion of solutions to related exercises for further learning.

Introduction
In this insight article, we will build all the machinery necessary to evaluate unit hypercube integrals by a novel technique. We will first state a theorem on Dirichlet integrals, second develop a sequence of nested sets that point-wise converges to a unit hypercube, and thirdly make these two pieces compatible by means of a Dominated Convergence Theorem, and lastly demonstrate the technique of integration. Note: The same technique is outlined (in the same way) in the expanded insight article entitled A Path to Fractional Integral Representations of Some Special Functions.

The Integrals of Dirichlet
Dirichlet integrals as I learned them from an Advanced Calculus book are just that formula evaluating the integral to Gamma functions, they are not a type of integral like Riemann integral, more just a formula that would go on a table of...

Thread 'Problem with calculating projections of curl using rotation of contour'
Hello! I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem. Given: ##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0## ##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1## ##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0## I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
