If you supply x as {-10 0} solver gives -3.04544793089 Sign Reversal, with 0: - 4.50061385902E-2 Extremum. It's up to you to decide which answer to use. You could also plot it and select interval there. HP50 and Prime have different accuracy therefore the two sides of equation may differ. BTW DM42 finds 'exact' solutions at sign reversal points like: -3.045447930881649697415605577746648 -5.997627340756129979223366652843795 -9.000117833796755710867792548726015 and others |
