If you use this expressions, you will get the minus for FD and plus for BE | |

| Jun 4, 2021 at 19:05 | comment | added | imbAF | how can that be? I have a plus there, not a minus. That's who we derived it | |

| Jun 4, 2021 at 19:01 | comment | added | imbAF | Exactly! But then it comes this 2nd problem in my script. Later we try to derive the grand canonical partition function for the case of continues energy/momentum values. If i make the change, then i should get a minus by then end for the FD case, while the professor, has no minus. What should i do??? | |
