In other words, we will find approximate values of the unknown solution at these mesh points.įor simplicity, we use uniform grid with fixed step length h however, in To start, we need mesh or grid points, that is, the set of discrete points for an independent variable at which we findĪpproximate solutions. However, it is important to study because comprehension of Euler's method makes error analysis easier to understand. The process proceeds, so it requires a smaller step size if greater accuracy is desired. It has limited usage because of the larger error that is accumulated as Euler's rule serves to illustrate theĬoncepts involved in the advanced methods. Such as create a graph, or utilize the point estimates for other purposes. The user can then do whatever one likes with this output, Will be returned to the user in the form of a list of points. Numerical solution to the initial value problem for first order differential equation.
