Other than guessing what is the formal way of solving following types of DE :
x^2 * u'' = k*u
or more generally :
x^n * u'' + x^m * u' = k*u
u is a function of x.
thanks.
Find a distribution F in R^2 that satisfies (Dx) F(x,t) = t*Delta(x)
It is apperantly not t*H(x) as in R.
* is multiplication, D is dirac delta, H is Heavyside , (Dx) is derivation with respect to x (in the sense of distributions)
Sorry for not using Latex.
Indeed I am trying to...
