Use Euler's method with the specified step size to determine the solution to the given initial-value problem at the specified point.
$$y^{\prime}=-\frac{2 x y}{1+x^{2}}, \quad y(0)=1, \quad h=0.1, \quad y(1)$$.

Key Concepts

Euler's Method

Euler's method is a simple, first-order numerical procedure used to approximate solutions of ordinary differential equations (ODEs) with an initial condition. It works by taking small, fixed increments along the independent variable and using the slope provided by the differential equation to estimate the new value of the dependent variable at each step.

Initial-Value Problem (IVP)

An initial-value problem is a type of differential equation accompanied by a condition that specifies the value of the unknown function at a particular point. This condition allows the unique determination of the solution among a family of potential solutions, forming the basis for numerical techniques like Euler's method.

Differential Equations (ODEs)

Differential equations involve functions and their derivatives and are fundamental in modeling dynamic systems. Solving these equations, whether analytically or numerically, helps in understanding how a system evolves over time or space based on changes in one or more independent variables.

Step Size in Numerical Methods

The step size, often denoted by h, is the interval between successive points in the numerical approximation process. In methods like Euler’s method, selecting an appropriate step size is crucial as it directly affects the accuracy and stability of the numerical solution—smaller step sizes usually yield better approximations but require more computation.
