Following the question "The \bar and \overline commands" which is simply about the lengths of both, I'd like to know when to use \bar and when to use \overline from a semantically viewpoint. I always ...

I am trying to typeset some higher-order time derivatives using the dot notation, and I've noticed something strange. The expressions $\dot y + y = \cos(\dot y)$ $\ddot y + y = \cos(\dot y)$ give the ...

I'm having trouble with the appearance of parentheses representing function arguments. They appear to far away from the function name. For example the code \left(1-f_{p}\left(l+1\right)\right)\...

If I write $\bar{X}$ or $\overline{X}$ the bar (or the rule) over X is smaller or longer than the width of X. Is there any way to adjust the width? Thank you in advance. MWE \documentclass{article} ...

I created a table in LaTeX, however, I can not put a space after the first row. As you can see the bar of X mean overlaps the \hline. I tried \\[1pt] after \hline, but it produced much more space than ...

I'm denoting the complement of the closure of the set $A$ by $\overline{A}^C$. This looks ugly, though (the C is too high up and not far enough to the right)--might there be any quick fixes?

I'm interested in using the standard \cup, i.e. and the one given by importing the mathabx \cup in the same document. Does anyone know how to do that?

I want to write this in LaTeX: However, $$\overline{S_n}^2 = \frac{1}{n}\sum\limits_{i=1}^{n}(X_i - M_n)^2$$ gives me: whereas $$\bar{S_n}^2 = \frac{1}{n}\sum\limits_{i=1}^{n}(X_i - M_n)^2$$ gives me: ...

I'd like to know how to but bars (like for example $\bar s$) directly above the letter of the field, for example above this $\mathbb{F}_p$, Any help would be appreciated.

With this code \documentclass{minimal} \usepackage{amsmath} \begin{document} ${\bar{S}}_{\text{rel,t}}$ \end{document} I get How can I extend the \bar over the subscript?

I think that most people are familiar with the fact that \bar creates a bar which is much too small, yet \overline creates a bar which is too long. I recently came across this excellent answer where ...
