Math & Science ⇒ Limit with multiline expression underneath

[XXX]

If I have limit with two variables x->x0 and y->y0, what is the command which let me right x->x0 under y->y0 and both under \lim? Is it possible in latex to right like that:

Lim
x->x0
y->y0

Hi,

you can use the \substack command:

Code: Select all

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\[
  \lim_{\substack{x\to a \\ y\to b}}f(x,y)
\]

\end{document}

It works! thanks a lot:)
