CTAN update: RetosMatematicos
by CTAN Announcements 02 Sep '26

02 Sep '26

Henry Díaz Bordón submitted an update to the RetosMatematicos package. Version: 1.1.2 License: cc-by-sa-4 Summary description: LaTeX template for the Telegram group Retos Matemáticos Announcement text: -------------------------------------------------------------------------------- This new version of the template introduces several new arguments for the `RetoPSTricks` class, which are listed below: * `tamfuente`: Font size of the picture, by default it is set to 10pt. * `estilopunto`: Style of the points in the picture, by default it is `o'. * `tampunto`: Point size, by default `4pt 0'. * `tamlinea`: Line width, by default 0.6pt. * `tamflecha`: Arrow size, by default `3pt 2'. * `unidad`: Unit of measurement, by default 3cm. Furthermore, the `\enfasis` command in the `RetoMatematico` class uses now the `align*` environment instead of `equation*`, which allows for alignment characters inside it, and thus multiline, emphasized equations. Finally, the following macros have been added too: * The inverse hyperbolic trigonometric functions are available via `\arcsinh` and similar. * `\NN`, `\ZZ`, `\QQ`, `\RR`, and `\CC` are added as substitutes to `\N`, `\Z`, `\Q`, `\R`, and `\C`; the latter are now _deprecated_. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/retosmatematicos More information is at https://ctan.org/pkg/retosmatematicos -------------------------------------------------------------------------------- Thanks for the upload.
