Hey, all. I'm wanting to type up a few ways to solve a neat Kleppner & Kolenkow problem, and I'd like to put a diagram I've drawn in. Here is what I'd like to insert: https://scontent-iad3-1.xx.fbcdn.net/hphotos-xfp1/v/t34.0-12/12358411_10205721788785508_1144239407_n.jpg?oh=8712c4f0c3d757bc66acdf4be568f5ba&oe=566E3EB9 I'm typing it up on Sharelatex, so I'll be using TikZ. The most I've ever done with LaTeX is here on PF, and the most coding I've ever done was back in 2008 on MySpace, so I'm not sure where to begin. Sorry for the massive image, by the way.
