Riccati Equation. An equation of the form is called a
Chapter 2, Problem 47E(choose chapter or problem)
An equation of the form
(18) \(\frac{d y}{d x}=P(x) y^{2}+Q(x) y+R(x)\)
is called a generalized Riccati equation.
(a) If one solution—say, \(u(x)-\)of (18) is known, show that the substitution \(y=u+1/v\) reduces (18) to a linear equation in 𝑣.
(b) Given that \(u(x)=x\) is a solution to
\(\frac{d y}{d x}=x^{3}(y-x)^{2}+\frac{y}{x}\),
use the result of part (a) to find all the other solutions to this equation. (The particular solution \(u(x)=x\) can be found by inspection or by using a Taylor series method; see Section 8.1.)
