Feynman's Technique to integration utilizes parametrization and a combination with other different mathematical properties in order to integrate an integral that is can't be integrated through normal processes like u-substitution or integration by parts. It primarily focuses on setting a function equal to an integral, and then differentiating the function to get an integral that is easier to work with, such as the integral of (1/2)*xe^(x^2) instead of just e^(x^2).
