July 27, 2020 - Errors due to the computer’s inability to do exact arithmetic are called roundoff errors. Since a careful analysis of roundoff error is beyond the scope of this book, we will consider only truncation errors. The simplest numerical method for solving Equation \ref{eq:3.1.1} is Euler’s method.

In these cases, we resort to numerical methods that will allow us to approximate solutions to differential equations. There are many different methods that can be used to approximate solutions to a differential equation and in fact whole classes can be taught just dealing with the various methods. We are going to look at one of the oldest and easiest to use here. This method was originally devised by Euler and is called, oddly enough, Euler’s Method.

At any state \((t_j, S(t_j))\) it uses \(F\) at that state to “point” toward the next state and then moves in that direction a distance of \(h\). Although there are more sophisticated and accurate methods for solving these problems, they all have the same fundamental structure. As such, we enumerate explicitly the steps for solving an initial value problem using the Explicit Euler formula. WHAT IS HAPPENING? Assume we are given a function \(F(t, S(t))\) that computes \(\frac{dS(t)}{dt}\), a numerical grid, \(t\), of the interval, \([t_0, t_f]\), and an initial state value \(S_0 = S(t_0)\).

January 26, 2020 - The Euler’s method is a first-order numerical procedure for solving ordinary differential equations (ODE) with a given initial value.

What if we want to find the value of the solution at some particular \(x\text{?}\) Or perhaps we want to produce a graph of the solution to inspect the behavior. In this section we will learn about the basics of numerical approximation of solutions. The simplest method for approximating a solution is Euler’s method 1 .

Numerical methods are algorithms to numerically approximate solutions of differential equations and Euler’s method is the most basic numerical method. The idea is simple: use the equation \(y' = f(t,y)\) to construct the tangent line to the unknown solution \(y(t)\) at a given point \(t\), ...

July 23, 2022 - ... Euler's method is a numerical technique used to approximate the values of a function based on its derivative, providing a more accurate representation than linear approximation alone.

It is an explicit method, meaning that the answer at the new time level is explicitly given in terms of the older time level(s). A basic implementation of Euler’s method is shown in euler. It expects the problem to be specified in the form of a function \(f\) of two arguments, an interval defining the time domain, and an initial condition.

March 27, 2026 - Euler’s Method is a numerical technique that approximates a solution curve by “walking” along it in small, straight-line steps.
