Member warned that the homework template must be used
I have been given that r = 1/u
and that r(dot) = (-1/u^2) *(du/dt)
How is r(dot) calculated? I don't understand the steps of how to get from r to r(dot)
From my understanding r(dot) should be the derivative of (1/u) with respect to time, but I don't understand how to get to the final answer.
Thank you very much!
