the ODE. The ODEs arise in many areas of Mathematics, as well as in Sciences and Engineering. In most applications, one needs to find explicitly or numerically a solution y(x) of (1.1) satisfying some additional conditions. There are only a few types of …

ODE: Existence and Uniqueness of a Solution The Fundamental Theorem of Calculus tells us how to solve the ordinary differential equa-tion (ODE) du dt = f(t) with initial condition u(0) = α. Just integrate both sides: u(t) = α + Z t 0 f(s)ds. It is not obvious how to solve du(t) dt = f(x,u(t)) with initial condition u(0) = α

Numerical Solution of Ordinary Di erential Equations of First Order Let us consider the rst order di erential equation dy dx = f(x;y) given y(x 0) = y 0 (1) to study the various numerical methods of solving such equations.
