Sorry, I typed out my restatement of my work incorrectly, my chain rule is correct on my paper, I just lost it in formatting.
dR/dt=(1/P)*dm/dt - (M/P2 )*dP/dt is where I have landed after your suggestion nrqed, I don't have a way of checking for correctness, so if you wouldn't mind giving me a...
3. My work thus far:
I have tried several different methods of rewriting equation (1) in terms of dR/dt, using leibniz notation (dy/dx = dy/du*du/dx) in the form of dR/dt=(dR/dt*dM/dt) but am missing some of the mechanics that I am forgetting. This is chiefly where I need help.
Good afternoon folks. I am getting ready to start a Planetary Physics course next week and have been doing some of the old homework that is posted on the course site. I am struggling to figure this one out and would love some help. It's been about 5 years since first year calculus, so I am a...
