I mean, if you wanna get really technical, the limiting shape when you increase sides of a regular polygon isn’t a circle, but an Apeirogon. Though if you could see an Apeirogon in its entirety it would be indistinguishable from a circle, so in the end it doesn’t change the final result

I don't think these 2 are the same. But maybe that's because I don't know what an Apeirogon is.

If you could see infinity, there would be a slight difference

OK, I checked the definition of an Apeirogon and I must say, accprding to its definition, it is not at all related to circles And @daniel_77 what does "if you could see infinity" mean? And how does it imply that an Apeirogon and a circle are different. They are not similar at all to start with.

A (degenerate) apeirogon is a circle in the context of projective geometry, but in affine geometry, where these types of mathematics are being done, they are completely different shapes.

@@angelmendez-rivera351 WOW! That's totally unexpected! Care to tell us what the definition in both contexts and explain the difference please?

I have no words to describe my wonder at this.

Well, in a sense for the visual proof, we recognized the telescoping series as the one we originally wanted to find

Is the limiting circle really that much larger? I would not have expected...

In this case, the circle should actually be infinitely large. It would just be a horizontal line

Not 100% if this is rigorous as a proof - seeing as there is no limiting shape (as you cannot have an infinitely large circle). To turn it into a proof, I imagine all you have to do is prove that the limit (of the numerical series) exists
