I was looking for some guidance on how to attack this problem.(adsbygoogle = window.adsbygoogle || []).push({});

Consider the nonlinear ODE:

y'(x)+y[tex]^{}2[/tex](x)+Ay(x)+B=0

(y prime + y squared with A and B constant coefficients)

Show that the solution is given by y=z'/z, where z(x) solves the second order ODE:

z''+Az'+Bz=0

(z double prime plus z prime with A and B constant coefficients)

Any advice would be greatly appreciated!

Thanks!!
