  1. Changed paragraph regarding analytic versus algebraic proofs. I don’t think it is possible to give a purely algebraic proof of Weierstrass’s original theorem, whose conclusion includes the statement that the power series are convergent in some neighborhood of 00. How could you, when this is an analytic statement? I think my edit might be what the original author intended.
