Nothing with infinity. By taking sufficient terms he was able to calculate the product of the limits. So strictly speaking he is not multiplying series at all, ONLY some of the partial sums and from these obtaining the limit. > > > > Newton used this approach in determining sine series through inversion. He knew that he might end up with a series that could no longer be summed as in the case of these example geometric series, but he also knew that if he could find a pattern, then he would be able to approximate the sine ratio. > > > > This is hard evidence that it's a very bad idea to define S = Lim S. > > > > How arc length was derived: > > > > https://drive.google.com/open?id=0B-mOEooW03iLeGt2ZlViMzNyYTg > > > > No doubt the majority of the morons on this site will not be able to produce sufficient inference to reach an AHA moment.

Particularly, this applies to infinite sums which are limits of finite sums.
I do not allow you to use concepts that are ill-formed or which I have not approved. Do you understand idiot?
