Second solve(e^y-y=0,y) returns [y = e^y] for me, not [y = e]. The result isn't really wrong, just not very useful. solve is not very smart. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=2494349&group_id=4933 ```
