The video tutorial explains the fourth-order Runge-Kutta (RK4) method, a numerical technique for solving first-order initial value problems. It begins with an introduction to the RK4 method, derived from the Taylor series expansion, and proceeds to set up an example problem. The tutorial details the calculation of K values, which are essential for approximating Y values at given points. The process involves iterative calculations and comparisons with true solutions to demonstrate the accuracy of the RK4 method. The video concludes with a completed table of results, showcasing the method's effectiveness.
