Question

Hi, need help trying to figure these system of equations.

Answer 1

How do I get from:\[\nu''(r)=\nu'(r)\lambda'(r)\]\[[\nu'(r)]^{2}=\frac{ 2\lambda'(r) }{ r }\]to this:\[\nu'(r)+\lambda'(r)=0\]

Answer 2

Does integrating work? Just guessing, can be wrong.

Answer 3

Differential equations?

Answer 4

Answer 5

v''=v'x'
(v')^2=2x"/r
v'+x'=0
let everything be a fn of r

Answer 6

Ok continue
