Hi, I have a problem solving this PDE:(adsbygoogle = window.adsbygoogle || []).push({});

(y^2)*u(x,y)''+2*y*u(x,y)'-2*u(x,y) = 0

Every derivate of u is in fonction of y.

What I tried:

I said that (y^2)*u(x,y)''+2*y*u(x,y)' = (u(x,y)'*y^2)' and make

v=u(x,y)'*y^2

then I tried to isolate u(x,y) and I arrive to u(x,y)=-v/y+C(X)

But I can't go much further... I am blocked right there. Thank You.
