Compare the document title (typically shown on the tab for browser with tabs) for these questions:
- programming - How can I use NestWhileList instead of While in this case?
- equation solving - Elimination returning true instead of correct answer
- Plotting difference between a function and its inverse function
The first two have a title that starts with one of the tags the question has (respectively "programming - ", and "equation solving - "). The last question is tagged too, but no tags appear in the title. Does anyone know why?
I like removing those starting tags from titles with a userscript and noticed this because my script failed by using the naive assumption that the tag is always present. What are the rules for how these titles are formed?
