How can I write a partial derivative with an arrow on top of it (pointing to the left and right)? For instance:

enter image description here

I've tried to Google it, but couldn't find anything (probably because I'm not sure what keywords to use). Any help is much appreciated.

Ahhh perfect! Thank you. I will accept this answer (but for some reason I need to wait for 3 minutes before I can do that?). – Hunter Jan 19 '14 at 0:25
@Hunter You're not allowed to accept an answer "too soon", so that more people can contribute before you "select". It quite makes sense, just the error/hint messages that come with it are not perfect ;) – yo' Jan 19 '14 at 0:47
@tohecz Thanks for the clarification; that does make sense. – Hunter Jan 19 '14 at 0:48
