Solving First-Order Differential Equation in Computational Physics Based on Fourth-Order Runge-Kutta Method with C Language

Abstract

In the paper, I study how to solve first-order differential equation in computational physics based on the fourth order Runge-Kutta method with C language. Firstly, first-order ordinary differential equation is briefly introduced from the perspectives of mathematical concept and physical significance. Secondly, the fourth-order Runge-Kutta method is elaborated. Then, combining C language with the above algorithm, a concrete application is presented to bring out this process. Finally, the advantages of C language in solving the problem based on fourth-order Runge-Kutta are summarized.
