| Dec 11, 2023 at 19:09 | comment | added | Tom Copeland | (cont.) In fact, some users have edited some of my posts beautifully but making the lines then extremely difficult to cut and paste for use in other venues or even for calculations via substitutions in specific applications. // Some twenty years ago I used a free app that made it very easy to produce reasonably-sized pdfs with nicely formatted multi-colored equations, but it disappeared a couple of years later and I haven't found a comparable one since. | |
| Dec 11, 2023 at 18:50 | comment | added | Tom Copeland | @MichaelHardy, limited personal time and availability of free, nice, efficient apps for publishing large pdf files in LaTex. I've got tons of written material that I haven't published yet. Any recommendations for stand-alone apps or for add-ons for Google docs? Of course, I use cut and paste for related entries / use (MO, MSE, OEIS, pdf, WordPress, Desmos, Wolfram Alpha) and don't regard it a necessity to perfect the formatting for each venue for aesthetic tastes. | |
| Dec 11, 2023 at 18:10 | comment | added | Michael Hardy | This is the first I've heard of that particular blog, and I notice that you've got lines that say things like $ n!\sum_{k=0}^n \binom{n-n}{n-k} \frac{(-x)^k}{k!} $ instead of $ \displaystyle n!\sum_{k=0}^n \binom{n-n}{n-k} \frac{(-x)^k}{k!}. $ Note not only the difference in sizes of some things, but the difference in formatting of the subscripts and superscripts on the summation sign, thus $\sum_{k=0}^n,$ with the subscript and superscript to the right of $\sum,$ versus $\displaystyle \sum_{k=0}^n.$ Why put them in inline style rather than display style when they're on a line by themselves? | |

| Jun 17, 2022 at 19:18 | comment | added | Tom Copeland | in the links, I show that the Pascal lower triangular matrix itself, ignoring the initial column of ones, contains the face vectors of the hypertriangles. E.g., (4,6,4,1) is the f-vector for the tetrahedron, encompassing 4 vertices, 6 edges, 4 triangles as facets, and 1 tetrahedron. | |
