How to I reset ? - Amer7 - 01-24-2022 02:05 PM Hello, My calculator was working fine, but from some strange reason its giving me wrong derivative results in CAS. For example [attachment=10315] - this is correct, but when i type the same example in my calculator it returns 0. I have tried inserting a paper clip into reset hole but same issue. - Yes in past I have assigned the values from derivative into d1, d2, a1 and so on. But every I clear them by pressing Vars- then User- and deleting them. I have also tried going Shift+Mem and clearing CAS, User variable, User but it still returns the wrong derivative answer. EDIT: For some strange reason when I enter into Spreadsheet app, and Press Home, then CAS it returns the wrong derivative. But when I enter Function app them press Home, then CAS it gives the correct derivative |
