Math & Science ⇒ How to make this particular capital B letter? Not \mathbb{}, \textbf{}, \beta (and \Beta does not work for me! why?)

How to make this particular capital B letter? I tried to search for that... but i do not know how i should - what should be the common path for that, beyound asking help, like here?

Is it not $\mathbb{B}$, \textbf{B} or $\beta$.

(And $\Beta$ does not work for me! Why? I have these packages in my source: amssymb, amsmath, siunitx, gensymb, physics, [T1]{fontenc}, [utf8]{inputenc}, [portuguese]{babel}, hyphenat.)

Hi,

it looks like \mathcal:

Code: Select all

\documentclass{article}
\begin{document}
$\mathcal{B}$
\end{document}

No additional package needed.

Hello, Stefan. "Math calligraphy" - so that was the secret. Exactly what i wanted.

Most questions i may do in the next days, maybe one or two weeks, are for the same kind of thing: something with a mathematic detail - which i probably found in the same book i read that "B", or a detail needed to write the answer of an exercise (of that same book) using LaTeX.

Thank you very much (:

Just this little issue, that i found by accident, trying to find that "mathcal B", remains:

In a file with all the mentioned packages, $\beta$ works perfectly, but $\Beta$ does not. And it seems they should both always work together:

https://en.wikibooks.org/wiki/LaTeX/Mathematics#Greek_letters

A file with

Code: Select all

\subparagraph{(g)} $ \beta $

compiles normally, but a file with line

Code: Select all

\subparagraph{(g)} $ \Beta $

gives the following error (i did not copy all pdflatex output, thinking it is not really relevant for this):

Code: Select all

! Undefined control sequence.
l.128 	\subparagraph{(g)} $ \Beta $
?

I guess there is no extra capital Beta since it is the common capital B.

There is a table a little down the page that does not show a capital beta. And even the part you mention has the following note:

Note that some uppercase Greek letters look like Latin ones, so they are not provided by LaTeX (e.g. uppercase Alpha and Beta are just "A" and "B" respectively).

Semantically speaking, all greek letters should be provided as commands, since they are different entities.

Feel free to post your questions! Just make a new topic for each new question, easier to see and to answer than in a long thread.

Of course i will do new threads, Stefan. This one is (or seems) an exception just because '\Beta' is among the options i tried for that special B i was looking for. And since it did not work, i imagine that what i wanted could be found with it working. So \Beta does not work for that note i missed.

Thank you again (:

No problem, and my comment was just a best practice comment for later even without referring to here, as the \Beta was here already.
