Try this in CAS: convert(0,14) Must be typed in lowercase. CAS only. RE: Prime with cocoa - jebem - 02-20-2014 12:04 PM Nice one! Mine did the same, using the most recent firmware update (Nov-25). After typing "convert(0,14)" in CAS window, the answer was prompted in the history area as: "CONVERT(0,14) with_cocoa" Surely the calculator must have a good reason for this kind of recommendation. I enjoy chocolate very much, thank you! After checking the wikipedia, apparently this can be related to the COCOA API framework? "Cocoa is Apple's native object-oriented application programming interface (API) for the OS X operating system". RE: Prime with cocoa - Dominik Holenstein - 02-20-2014 01:20 PM Strange or interesting at least! convert(1,14) -> with_f5 convert(2,14) -> tdeg convert(3,14) -> plex convert(4,14) -> revlex convert(5,14) -> modular_check convert(6, 14) -> 6 This seems to be related to xCAS which is the base for the CAS on the HP Prime: http://www-fourier.ujf-grenoble.fr/~parisse/giac/doc/en/cascmd_en/cascmd_en232.html CoCoA has nothing to do with Cocoa on OSX and it is a system for computing with multivariate polynomials. http://cocoa.dima.unige.it/flyer4.html Further, CoCoA is part of xCAS. Computations in Commutative Algebra Dominik RE: Prime with cocoa - jebem - 02-20-2014 04:23 PM Thanks for the enlightenment, Dominik! That explanation makes all the sense now. I guess I have a long way in front of me to learn all this advanced CAS/xCAS framework. I did symbolic calculus at school in my time, long ago, but never used machines for that purpose, except of course for numeric operations with my HP-25 Jose Mesquita RE: Prime with cocoa - parisse - 02-20-2014 07:33 PM Yes, CoCoA was the Groebner basis computation engine of giac before I implemented my own engine (that is now the fastest open-source Groebner basis engine for revlex ordering). with_cocoa is still an optional argument that you can pass to gbasis in Xcas to force use of CoCoA.
