Differential Equations

Not sure it helps but have you looked at the equation when you make the substitution recommended for the Riccati equation, i.e.
y = \(\displaystyle \frac{u'}{a u}\)

I thank. but the Riccati equation y =? special solution y = y 1 + 1 / u do not solve the equation :(


Riccati EQUATION
p (x), r (x) and g (x) integrable function and r (x) ≠ 0, including
y '= p (x) y + r (x) y2 + g (x)
Type in the differential equation 'Riccati Differential Equation' is called.
If r (x) = 0, linear differential equations,
g (x) = 0 takes the form of the Bernoulli equation.


As a general solution y = y 1 + 1 / u conversion is done
 
y is certainly of the form
y '= p (x) y + r (x) y2 + g (x)
In this case p(x) = 0, r(x) = -a, and g(x) = b e-bx if I am reading the image correctly.

Do you mean you don't know the solution for the second order homogeneous ordinary differential equation which is the result of the replacement of y by
y = \(\displaystyle \frac{u'}{a u}\)
I haven't looked in detail at that equation so I'm not sure whether the substitution will help.
