SUMMARY
The discussion focuses on solving the Cauchy-Euler differential equation given by x²y'' - 2xy' + 2y = x with boundary conditions y(1) = 0 and y(2) = 0. The equation is confirmed as a Cauchy-Euler equation, and the characteristic equation is derived as r(r-1) - 2r + 2 = 0, yielding roots r = 2 and r = 1. A particular integral is proposed using the form y = Ax ln(x), which successfully addresses the non-homogeneous part of the equation. The transformation x = e^t simplifies the equation to one with constant coefficients, facilitating the solution process.
