    Best sky viewing apps for iPhone

    Sky Guide is hands down the best app for iPhone that I've tried. It's visually stunning compared to most apps of the same kind, and it's easy to use. It does cost money though, but it's well worth it with all its neat features.

    Euler's method for rocket equation with gravity and drag

    No, I can't find anything on the subject that I can use, I have been looking for days now. Anyway, thanks for your help.

    Euler's method for rocket equation with gravity and drag

    Thank you! Atleast I now know what's wrong with the whole thing. I have some questions though. I am not familiar with the up arrow in this quote -> ##t \uparrow b##, would you mind explaining what it means in that context? And it looks like I need to rewrite my equation, but I am way too tired...

    Euler's method for rocket equation with gravity and drag

    Thanks for your input, but I am afraid it is still not working. I think I may be doing something wrong, but I'm not sure. I'll keep trying though, see if I maybe stumble upon a solution by accident..

    Euler's method for rocket equation with gravity and drag

    Hello all, I am currently trying to solve a differential equation numerically. The equation is as follows: dv/dt = (u*q)/(m0-q*t) - g - (cd*ρ*A*0.5)*v2 If you haven't already guessed, it's the rocket equation with added gravity and drag. Now, I'm not even sure if that's what it's supposed to...
