a bit more sophisticated solution, please!

Unfortunately not. It's not a Bernoulli? DE.

Hi all, I have a nonlinear differential equation and I need to find an analytic solution for it. Here it is: \ddot{S}=-{1 \over 6} \dot{S}-{2 \over 7}(1-S)^2(- \dot{S})^{1.3} I have used a transformation to simplify it: -\dot S = v and came up with this DE which I couldn't solve...
