When I use \left(
and \right)
to get appropriately sized parentheses for an operator, a space is created between the operator and the parentheses. I think it looks bad. Is it intentional? If so, why? If not, is it easy to 'repair'?
\documentclass{article}
\usepackage{amsmath}
\usepackage[active,tightpage]{preview}
\PreviewEnvironment{align*}
\begin{document}
\begin{align*}
\log(a) &= 0\\
\log\left(a\right) &= 0\\
\log\left(\frac{a}{b}\right) &= 0
\end{align*}
\end{document}
Gives the following output:
\bigl
and\bigr
variants (there are four left and four right), which also classifies as open/close and thus no space is inserted. For the autoscaled, see themleftright
package. – daleif Apr 2 '19 at 8:54
