HP Prime G2 and CAS cosmetics (cube root) - F22Dead - 01-10-2022 08:40 AM
Hello, I am new to this forum. I got a new HP Prime G2. Nice machine! Already updated it to SW version: 2.1.14603 (2021 12 02) (HW ver. D; CAS v1.5.0; OS V2.060.650) I have a question about CAS display output. In the HOME settings I have "Textbook Display" and "Intelligent Math" checked. In CAS, Square Roots display very nice in input and output, but cube roots display as fractions (i.e. 1/3). The question is if this is working as designed (written), or if am I doing something wrong, missing an option/combination. To be more clear, I can enter a cube root (Shift+Xy) where the "3" is left of the radical sign, but the output is alwasy in fraction format. Comments and/or suggestions would be very much appreciated. RE: HP Prime G2 and CAS cosmetics (cube root) - IHarwell - 01-12-2022 09:46 AM
I can't seem to replicate what you're describing. Would you mind posting a screenshot of the settings pages for Home and CAS, as well as one showing the fractional display behavior? RE: HP Prime G2 and CAS cosmetics (cube root) - Joe Horn - 01-12-2022 01:54 PM

Thank you for the reply. The requested settings information: [attachment=10275][attachment=10276] [attachment=10277][attachment=10278] The reported problem: [attachment=10279] Of course (3 * 7^(1/3) ) / 2 is the correct answer, but I wonder if this "cube root" could be displayed nicer. Thank you beforehand for your comments and suggestions. RE: HP Prime G2 and CAS cosmetics (cube root) - IHarwell - 01-13-2022 09:47 PM
I'm not sure how to get it to show the root form with numbers. I would be surprised if there were a way based on what I found looking into the issue. This also happens with the official build of xcas that the HP Prime uses. While the Prime has a custom formatting system that sits on top of xcas, they probably missed this case since xcas gives very different answers for these two cases. ** For any HP programmers out there ** If I were to hazard a guess, I'd probably check the textbook formatting algorithm to make sure it looks for "1/_" form exponents as well as the xcas "surd" or "NTHROOT" function and displays them as nth roots. In the case of "1/_", it should probably revert to "NTHROOT" form when the "_" is either a symbolic leaf, a constant, or an integer/integer-like number. This would probably need a new option to control the behavior, though. |
