LyX ⇒ Macro in Lyx

[bobred]

Hi
I am trying to get a macro that takes 2 argument and displays the derivative of x to order n. I type the following onto the Lyx page

Code: Select all

\newcommand{\diff}[2]{\dfrac{d^{#2}}{d#1^{#2}}}

when I highlight and go to and press Ctrl+M I get a macro, that works. I would like a way that I can hide this macro, in the preamble would be good. I have tried copying the source code into the preamble but the macro doesn't work then.

Hi James,

did you manage to solve the problem?

I have tried copying the source code into the preamble but the macro doesn't work then.

"Doesn't work" maybe, but it's not a problem description that we could work with. Any error message? Perhaps post a minimal working example. Either LaTeX export (for non-LyX users like me - LyX is just LaTeX with front-end ) or a .lyx file as attachment here.
