Key Concepts

Ordinary Differential Equations

Ordinary differential equations (ODEs) involve functions of one variable and their derivatives. They are used to represent problems where the rate of change of a variable is related to the variable itself and possibly other factors, and they model many physical, biological, and economic phenomena.

Initial Value Problem

An initial value problem is a type of differential equation accompanied by a specified value of the unknown function at a particular point. This initial value serves as the starting point for finding the solution curve, ensuring the problem is well-posed for methods like analytical or numerical integration.

Euler's Method

Euler's Method is a simple and widely taught numerical technique for approximating solutions to initial value problems for differential equations. It involves using the derivative at a point to estimate the value of the function at a subsequent point by taking a fixed step along the tangent line, thus constructing an approximate solution incrementally.

Step Size

Step size is the incremental value of the independent variable used in numerical methods such as Euler's Method. The choice of step size affects both the accuracy of the approximation and the computational cost, with smaller step sizes usually yielding more accurate results but requiring more computations.
