I updated the firmware about one week ago. but just in case i re-installed HP Prime virtual calculator in my computer set it to factory settings and updated the firmware (to see if the problem was my calculator or the settings) , it seems that if i use approx() it works but still don't know why this happens

The issue has to do with "tiny elements," which are normally "converted" to 0 in the non-CAS environment. If you use the CAS view, your inverse will work fine. I hope that in the future the developers might consider a "tiny element" setting (convert to 0 or leave as-is) so that this issue can be resolved in the Home view as well.
