In an answer, I wanted to write , but that wasn’t showing. I think it wasn’t showing for Markdown.

So I thought I should use \tilde, but it came on top of the next letter. How can I write down tilde in MathJax?


1 Answer 1


is a small space, while \tilde{} is an ornament of a character. Use instead e.g. \sim. More generally, for such LaTeX questions, check out Detexify.

    $\begingroup$ Minor note: if the spacings don't look right, use {\sim}. The bare \sim is a binary operator and is spaced accordingly, which might be too much space for several common applications. $\endgroup$ Feb 21, 2022 at 9:55
