Do you need it DISPLAYED that way, or do you actually need it changed to just "10/11"?
If you just need it to display that way, go to layout mode, click on the field in question, and format the display to include just the month and day.

there are many ways to do this. I assume your result is text, not date. If it's a date, you need to look at formatting instead.
Here's one way:
month ( $aDate ) & "/" & day ( $aDate )
+1 if display use this method, if calculated use David's
