# [Tex/LaTex] A problem caused by mathabx package

mathabx

I am sorry, but I don't usually know the meaning of LaTeX codes, I just copy them. I want to use this command:

\newcommand{\acts}{\mathrel{\reflectbox{$\righttoleftarrow$}}}


And, to use this command, I wrote

\usepackage{mathabx}

\usepackage{epsfig}


above.

Also, in my cover page I have the codes (given by the university)

\title{THESIS TITLE}

\degree{B.S, My Department, My University, 2013}


When I run it, I get the error

!Latex Error: Command '\degree' already defined. See the latex manual …

Also, when I say "go to error" it goes to the last line of my first definition, that is

\begin{defn}{\label{somedefinition}}

Here is the first line of the definition

The second line of the definition **(the error sends me here)**

\end{defn}


Any solution to this problem is fine, and I appreciate any help. Thanks.

Replace

\usepackage{mathabx}

\usepackage{epsfig}


by

\let\savedegree\degree
\let\degree\relax
\usepackage{mathabx}
\let\degree\savedegree

\usepackage{graphicx}


The \let just temporarily undefine \degree and so the package does not complain, then puts the thesis class definition back.

The epsfig package should not be used, so that's an unrelated change.
