Moon Rocket Lander. - ggauny@live.fr - 04-14-2016 09:34 AM
Hi,
In my search to do my program, which is not yet finished because so hard to
do, I was looking for all litterature I have on this subject.
I've found this in an old HP 65 notes I have. But in this HP65's game we've
120 fuel units, like in HP25, but in HP67 we dispose only 60 units.
How can I change this formulaes to get the solution for how many burns of
how many units ?
May be mathematicians can help me ?

This is a problem which the Prime is uniquely qualified to solve. Type the equations into the numeric solver:

Type in Vo, So, and g; then guess values of t until b is an integer:

Sorry for hijacking a general forum question with a prime answer.
