Jordan Rosenthal had a question about FourierTransform.
As part of the question he wrote:
--------------------
<snip>
I ran the following code
FourierTransform[Sign[t], t, w, FourierParameters -> {1, -1}]
and got the following result
\!\(\(-2\)\ \[Pi]\ DiracDelta[w] +
2\ \((\(-\(\[ImaginaryI]\/w\)\) - \[Pi]\ DiracDelta[w])\)\)
Is there a better way to copy an output into a posting?
All those backslashes seem to be a bit confusing.
--------------------
I expect multiple members of the group will answer your question about
Fourier, so I won't get into that. However, I do have a unique perspective
on formatting output for email.
You can format the output using InputForm and the output often comes out
very good. But InputForm is sometimes very annoying. I wrote a package that
formats output like InputForm without the annoying traits. You can download
the package from
http://www.mathsource.com/cgi-bin/msitem?0210-902
The package defines a function called PlainForm.
Load the package, evaluate the following and all your output will be easy to
read in email.
$PrePrint=PlainForm;
