Hi all:

Is there a way to write $a_n\rightarrow_{x\rightarrow 0}\,1$ but making the x-->0 appear UNDER the right arrow? I can't find an example of this anywhere, and then I have to write lim_ all the times.
Thanx
Tonio

Like this: $a_n \xrightarrow [x \rightarrow 0] {} 1$

The code is $$a_n \xrightarrow [x \rightarrow 0] {} 1$$

3. $$a_n \xrightarrow [x \to 0] {} 1$$

This is a bit shorter and work as well
