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 ?

must be disabled the automatic simplification, also happens to factor() cmd

Thank's !! It's Ok with "simplify level fixed at minimum"...
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)
