hp 39gii solve
Is there a way on the hp 39gii to solve for roots of a differential equation (other than graphically)? When looking at the manual, the differential equation asks for a specific "x" to give the f'(x) at that point. Don't know if differential equations can be used in solve...

I guess this topic is outdated, but how do you understand that "roots of differential equation"? As I can see in the topics, you are a 39GII user try to dive into the deep. As per your experience: how long the batteries lasts if you use regularly the calc? Where OS update can be found? Which kind of cable applicable? My unit is arrived yesterday  really interesting machine. Thanks, Csaba
