Euler method - Wikipedia
https://en.wikipedia.org/wiki/Euler_method
In mathematics and computational science, the Euler method (also called forward Euler method) is a first-order numerical procedure for solving ordinary differential equations (ODEs) with a given initial value. It is the most basic explicit method for numerical integration of ordinary differential equations and is the simplest Runge–Kutta method. The Euler method is named after Leonhard Euler, …

f ( x + 3 h) f (x+3h) f (x+ 3h). At each step, we use the slope of the curve to construct the next line segment, and this allows us to "follow" the curve with line segments, as shown in the image to the right. This number. h. h h is called the step size, and measures how small the approximating segments are.
