I don't know why but my greek letter eta refuses to become italic. Any ideas?
Here is a minimal example:
\documentclass[12pt]{report}
\usepackage[a4paper,width=150mm,top=25mm,bottom=25mm,bindingoffset=6mm]{geometry}
\usepackage[onehalfspacing]{setspace}
\usepackage{ucs}
\usepackage{mathptmx}
\usepackage[ngerman]{babel}
\usepackage[T1]{fontenc}
\usepackage{amsmath,amssymb,amstext,amsthm,mathtools}
\begin{document}
$\eta = 1$
\end{document}
Unfortunately, the eta looks just normal. Why does it not turn italic?
Best Answer
The package
mathptmx
provides Times-like fonts, but it's a 35-year-old hack and for Greek letter it uses glyph from the slanted Symbol font.You get better results with NewTX.
The package
ucs
is obsolete and does nothing really useful here. Alsoamssymb
should not be loaded along NewTX, because this one already provides the needed symbols. Note thatamstext
is automatically loaded byamsmath
.
