Beautiful Geometry behind Geometric Series (8 dissection visual proofs without words) #math #series

This video is a compilation of eight shorter videos I have created showing dissection proofs for infinite geometric series with ratio of the form 1/n and first term 1/n. To see the original videos (in shorter form and typically with more dramatic music), check the links below. When you have seen enough of these dissections, you should be able to guess the general formula for such a geometric series (and perhaps the more general form, which can be found in other videos on my channel).

Here are the original series videos (along with attribution; for more detailed attribution, see the original videos):
