Bachelor's Thesis

This bachelor thesis is dedicated to the systematic processing and practical application of Feynman's integration method, formally known as differentiation under the integral sign (Leibniz's rule). The theoretical part formulates key theorems on interchanging the order of differentiation and integration, and derives the necessary combinatorial, trigonometric, and integral identities. The practical section demonstrates the power of the method on problems involving transcendental functions, Fresnel integrals and other problems. The main contribution of this thesis is the formulation of an original analytical algorithm for the complete evaluation of the generalized Dirichlet integral. The resulting analytical expressions, which standard computer algebra systems fail to solve analytically, are successfully verified in the conclusion using numerical integration in Wolfram Alpha software.
