Does anybody suggest how to face the inhomogeneous Bernoulli differential equation
$y'+P(x)y=Q(x)y^n+f(x)$
for the simple case $f=const.$ and for the generic case.
I would like to know about techniques of approximation, bounds, asymptotic limit, numerical techniques etc.
Thank you
Roberto



Inhomogeneous Bernoulli Equation
I presume your $f(t)$ should be $f(x)$. This is Chini's equation. See e.g.
