(/thread-252121.html) HP Prime can't find how to use partfrac function ! - dg1969 - 10-04-2013 Hi, When I try the example include with the help of "partial fraction" in the emulator : 2013-8-13 (5106) CAS 1.1.0 CAS>Algebra>Partial Fraction partfrac(x/(4-x^2)) the emulator answer : -x/(x^2-4) !! in place of (-1/2)/(x-2) + (-1/2)/(x+2) I'm missing something ? Re: HP Prime can't find how to use partfrac function ! - CompSystems - 10-04-2013 must be disabled the automatic simplification, also happens to factor() cmd Re: HP Prime can't find how to use partfrac function ! - dg1969 - 10-04-2013 Thank's !! It's Ok with "simplify level fixed at minimum"... And thank you mister Parisse for the partfrac shortcut : sto + Edited: 4 Oct 2013, 9:22 a.m. Re: HP Prime can't find how to use partfrac function ! - Joe Horn - 10-04-2013 Quote:And thank you mister Parisse for the partfrac shortcut : sto + And thanks too, Bernard, for the CAS factoring shortcut: sto * 153 sto * Enter --> 3^2*17 x^4-1 sto * Enter --> (x-1)*(x+1)*(x^2+1) (Note: the sto * shortcut doesn't use i to factor polynomials, even if that flag is set in CAS Settings)
