A set of new features in LaTeX

Question

So I have a little question:

What is the “best way” for a set of new features in LaTeX that are not yet included in various packages? Right now, I just use \mboxgo-to as my method, but I'm just wondering if there is a more acceptable way to do this (as in the case of mbox, I should definitely include spaces in the function text so that it does not look too strange)

Here is an example:

$y(t)=2e^{1/2}\sqrt{\pi}\mbox{Erfi }(t)$

which is as follows:

$ y (t) = 2e ^ {1/2} \ sqrt {\ pi} \ mbox {Erfi} (t) $ http://adamnbowen.com/images/error_function.jpg

Don't get me wrong ... I think everything looks good, but I was just looking for some opinions (as far as best practices are concerned).

Answer 1

\DeclareMathOperator(or, if you're using some weird LaTeX distribution that doesn't have AMS packages, \mathop{\mathrm{Erfi}})

See the always useful British TeX FAQ, in particular the Definition of a new log-like function in LaTeX .
