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I guess this topic is outdated, but how do you understand that "roots of differential equation"?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
