Euler's Method

Euler's Method is a numerical approach for approximating a solution to a 1st order differential equation.

Using the approximation, f(x + h) ≈ f(x) + F(x, y) h , where h is the step size and F(x, y) is the gradient function (i.e. 1st derivative) of f(x), we can approximate the value of with increasing accuracy as we shrink the step size.
