Answer zero, it returns 0 (incorrect!). Now, try q1: ev(q,a=1) tlimit(q1,e,0) correctly returns 1. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=600469&group_id=4933 ```

(You might think this has something to do with the value of 0^0, but it does not -- the definition of limit only depends on the cases where q <> 0, and I hope we all agree that q^0 = 1 when q is non-zero.) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=600469&group_id=4933 ```
