As it does that, it's getting successive approximations to w. Typically, it never quite gets there, but after about a dozen steps, we're up to w = 2.999, which is close enough.
A medida que lo hace, se logra aproximaciones sucesivas a W. Por lo general, nunca llega allí, pero tras una docena de pasos, estamos en W = 2.999, que es lo suficientemente aproximado.
