Hello,
I'm puzzled about
sage: var('a,t')
sage: y = function('y')(t)
sage: desolve(diff(y,t)-(2*t*y-6/t-6/t^3), y).simplify_full()
_C*e^(t^2) - 3*Ei(-t^2)*e^(t^2) + 3*e^(t^2)*gamma(-1, t^2)
because c*e^(t^2)+3/t^2 is (also?) a solution to this ODE according to
Wolfram.
So, is the second solution a simplification of the first (and so this a bug
in Maxima),
or are both solutions valid (meaning perhaps they are both not the general
one?)?
Regards,
