# Please be careful when using TeX/MathJax in _titles_! This is more on how _not_ to use MathJax, but still good to keep in mind. A good overview of why not to use do this is given [here](https://cs.meta.stackexchange.com/a/1440), but let me briefly summarize: 1. Titles are visible in places that do not render TeX! 2. If you must describe your title with TeX, you probably aren't summarizing your question enough. Try to make a natural language title, that is usually possible and summarizes your question better. 3. If you _insist_, then by all means, use TeX in the title. But there's always room for improvement. IMO, TeX in title is _never_ necessary and a sign that the title can be improved!
