Worked Example. Use Euler’s method on \(\large\frac{dy}{dx} ormalsize=2y, y(0)=1\) with \(\Delta x=1\). From now, \(\Delta x\) means the change in \(x\) from one point to the next – that’s the step size! The solution to this ODE is \(y=e^{2x}\), which you’ll see from \(\large\frac{d}{dx} ormalsize(e^{2x})= 2e^{2x}\).

Explanation: We start at x = 0 and move to x=2, with a step size of 1. Essentially, we approximate the next step by using the formula: . So applying Euler's method, we evaluate using derivative: And two step sizes, at x = 1 and x = 2. And thus the evaluation of p at x = 2, using Euler's method, gives us p (2) = 2.
