Latex experts: Using CAS it generates for abs(x) using \mid ... \mid, which makes the vertical bars too much spaced out, vs. using \left| ... \right|
What do folks think about this? What do you use for abs(x)? Here is MWE, and screen below it
\documentclass{book}
\usepackage{amsmath}
\begin{document}
\[
\ln \! \left({\mid 1+x \mid}\right) = x
\]
\[
\ln \! \left( \left| 1+x \right| \right) =x
\]
\end{document}
