It seems that coefficient() gives the result as a function, because if i look with show(b) What can I do better or is this just not possible with sage code? Thanks Ps. The notation of higher order derivatives of symbolic functions should be better than D[0,0,...,0]f(r). Hopefully someone fixes it. |
