How can we solve a differential equation of the form $$a(r)Y' = Y - Y^2$$ for ##Y \equiv \phi(r)##? An equation of this form appears in https://en.wikipedia.org/wiki/Deriv...field_equations_to_find_A.28r.29_and_B.28r.29. If there were not the ##Y^2##, that would be a easy to solve differential equation: just a first order linear differential equation. The problem is the ##Y^2## though.
