| May 21 at 2:46 | comment | added | Kapil | It is interesting that the quote in the link in another answer by Jacobi indicates that he does not entirely concur. | |
| May 20 at 18:18 | comment | added | Pedro Lauridsen Ribeiro | Triple cross products always do in the case of three non-collinear but linearly dependent vectors, that's the point. | |
| May 20 at 16:59 | comment | added | LSpice | Re, thanks! I had figured that must be the Jacobi identity in question, but it hadn't occurred to me that the relevant triple cross products would lie back in the original plane, so I hadn't been sure how to interpret it. | |
| May 20 at 16:41 | comment | added | Pedro Lauridsen Ribeiro | Unfortunately he doesn't, at least not in this reference... this specific fact refers to the Jacobi identity for the cross (vector) product in $\mathbb{R}^3$. A proper outline of this argument can be found e.g. in khudian.net/Etudes/Geometry/jacidentandheights2.pdf | |
