Re: ROOT bug? HP 48S/48G Message #6 Posted by Gilles Carpentier on 13 July 2012, 4:03 a.m., in response to message #1 by Eddie W. Shore
Same result with the 50G, using ROOT
Note that on the 50G, in approx mode :
'X^3+5*X^22*X+7' SOLVEVX
gave the 3 roots (in complex mode, 1 in real mode)
{ 'X=(.291415279138,1.08116667823)' 'X=(.291415279138,1.08116667823)' 'X=(5.58283055828,0.)' }
but is unable to find the exact roots
I don't remember if SOLVEVX exists in 48 series
