Kevin, 9 year old, can derives difficult integral formulas super fast, This Reduction formula of integral of tangent power of n is from integral table.
He had turned most of integral methods into his own components needed for integration. Here he demonstrates the continuous flow of integration process like a snake move on wet grasses. As a result modification, He makes integration process short, fast and easy.
For those who know calculus may wonder where are the integral methods? The kid had been modified and embedded these methods as needed to keep process moving. For every integration he does , he just ramps the problem from beginning to the end.
This is integral calculus formulas #31.
