(1986): Numerical Treatment of Singular/Dicontinu form of ordinary differential equations (ODEs) which cannot be solve analytically many scholars have worked by using single step and multistep methods with. Numerical methods for solving a single, first-order ODE of the form / = ( ) can also be for a single equation.
