Suppose you have an ordinary first order differential equation in the form [math]y'\left(x\right)=f\left(x,y\right)[/math].[br]Input your [b]equation's right side[/b] [math] f\left(x,y\right)[/math] into the first input box.[br]Use the next two input boxes for the [b]initial condition[/b].[br][math]x_{max}[/math] is the [b]maximum x-value[/b] for your numerical solution.[br]The slider for h determines the [b]stepsize[/b] in the Euler method.[br][br]The solution from the Euler method is [b][color=#351C75]purple[/color][/b].[br]For comparison there is the [b][color=#e69138]orange[/color][/b] curve, that is generated with GeoGebra's [url=https://wiki.geogebra.org/en/NSolveODE_Command]NSolveODE[/url] command, which uses a more sophisticated numerical algorithm.
