Math & Science ⇒ length of value bars

[michael_b]

Hi all!

Does anybody know how i can vary the value bar?

e.g. on the picture you can see the value bar includes the text "grenzwert a=0!". i only want the value bar to be as long as the fraction.



my code looks like:

Code: Select all

\documentclass{article}
\usepackage[sumlimits,intlimits]{amsmath}
\begin{document}
\[\left|\frac{1}{n} - \underbrace{0}_{\text{Grenzwert }a=0!}\right| < \frac{1}{100} \hspace{5mm} \Leftrightarrow \hspace{5mm} n>100\]
\[\left|\frac{1}{n}\right| < 10^{-8} \hspace{5mm} \Leftrightarrow \hspace{5mm} n>10^8.\]
\end{document}

Hi,

instead of the \left...\right construct you could use one of the commands \big, \Big, \bigg or \Bigg:

Code: Select all

\[\bigg|\frac{1}{n} - \underbrace{0}_{\text{Grenzwert }a=0!}\bigg| < \frac{1}{100} \hspace{5mm} \Leftrightarrow \hspace{5mm} n>100\]
