It's not totally rigorous, but it wouldn't be hard to fill in the details. This is a sketch of a proof, not the proof itself.

- karthickgururaj 4y agoYes, that's basically what I said and meant in the parent post. I was suggesting the article call it a "graphical" solution approach, not analytical. And if I wasn't clear - it wasn't my intent to treat this any less "useful". If anything, it is more interesting (for me) to read about solutions that give an intuitive feel, than dry analysis.

Take for example this proof of the Pythagorean Theorem: https://cdn.britannica.com/43/70143-004-CCB17706/theorem-demonstration-squares-proof-Pythagorean-b-square.jpg?s=1500x700&q=85 https://cdn.britannica.com/43/70143-004-CCB17706/theorem-dem...
