I'm new to LyX. I'm writing my next homework with it to give it a try. My example code is below:
% Preview source code
%% LyX 2.0.5.1 created this file. For more info, see http://www.lyx.org/.
%% Do not edit unless you really know what you are doing.
\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{babel}
\begin{document}
This is an expression with dfrac:
\[ f(x) = \dfrac{2}{x} \]
\end{document}
Under another question, they offered me to use \dfrac
fractions for a better view. However, using dfrac
causes compiler error like below:
I thought this error with dfrac
may be due to not using the amsmath
package. I went to Menu > Document > Settings > Math Options
, I unchecked Use AMS math package automatically
and I checked Use AMS math package
. LyX added \usepackage{amsmath}
and \usepackage{amssymb}
lines into the source code. Now when I try to preview my article in PDF format, it gives LaTeX Error: File 'amsmath.sty' not found.
error.
I used to use online Latex editors, then copy screen shot of their output and paste it into MS Word. It was so simple doing that way. Now all these packages, uneditable source code, and all these complexity for writing a simple fraction is making me too frustrated. I have started to question if I did the right thing with switching to LyX. Because those online editors perfectly displaying that dfrac
fraction in my example.
How do I write a simple dfrac
fraction after opening a new article from Menu > File > New
in a fresh LyX 2.0.5.1 installation?
