I want to have a symbolic solution of this third order linear ODE with Maxima "odes" package:

y''' 6 y'' * - 11 y' * + 6 y * - 3 x * ≡

But Maxima does not recognize the differentiation operator:

Even in SMath I cannot symbolically show the differentiation operator, it interprets as zero:

a b c d k f 61 sys x y 2^+ x atan sin x y x diff + y x 2 diff y x Diff'diff(y,x) str2num 61 sys MaximaDefine x y 2^+ x 1 x 2^+ sqrt / x 00061 sys

x y x 2^sin * + x y x 2^sin * +

x y x diff + 3 y * x 2^* - x 0 + 3 y * x 2^* -

y x 2 diff 0

y x diff 0
