Then and now the main developer of Euler is René Grothmann, a mathematician at the Catholic University of Eichstätt-Ingolstadt, Germany. In 2007, Euler was married with the Maxima computer algebra system.

The Euler method is a numerical method that allows solving differential equations ( ordinary differential equations ). It is an easy method to use when you have a hard time solving a differential equation and are interested in approximating the behavior of the equation in a certain range.
