Hello,
I am quite new to SAGE but I think I've found a problem with the
latex(math-expression) command. I've tried with version 2.8.6, 2.8.7
and 2.8.8.1:
The problem seems to be the abs() command. Take any function like
f(x)=2*abs(x) with a changing sign. Entering now latex(f) shows me as
the result:
x \ {\mapsto}\ {2 \cdot \abs \left( x \right)}
Compiling this with LaTeX I cannot see the mathematical sign for abs
( preferred \left| (...) \right| ), but simple brackets. Furthermore
the LaTeX compilers tells me of errors: !undefined control sentence
In fact, \abs is no known latex command to me. Deleting \abs removes
the latex compiler error, of course, but thats not the correct latex
code for my expression for f(x).
The following packages have been included for compiling in latex:
\usepackage{ngerman}
\usepackage{color, framed}
\usepackage{graphicx}
\usepackage{amsmath, amsthm, amssymb}
\usepackage[automark]{scrpage2}
I don't know if I've done something wrong or if this is a bug or if
its even supposed to be that way. So I'ld like to ask you: what can I
do?
How can I get the right result as latex code, if its neccessary to use
absolut values of functions or parts of functions?
Thanks for your help,
marko
