I have two problems that confuse me for similar reasons. The first one:
Find the potential $\varphi$ of an uncharged conducting sphere outside of which a point charge $q$ is located at a distance $l$ from the sphere's center.
The second one:

I have a Graph with multiple edges between two vertices. Of course, I want to label them differently. (Or, more generally, give them different properties such as weight or style).Unfortunately, WL seems to treat m... | {"extraction_info": {"found_math": true, "script_math_tex": 0, "script_math_asciimath": 0, "math_annotations": 0, "math_alttext": 0, "mathml": 0, "mathjax_tag": 0, "mathjax_inline_tex": 0, "mathjax_display_tex": 0, "mathjax_asciimath": 1, "img_math": 0, "codecogs_latex": 0, "wp_latex": 0, "mimetex.cgi": 0, "/images/mat... |

A little while ago, I wrote a PPCG challenge under the tag, which frankly bombed.
Briefly, the challenge was to output a series of names.
