Hi, I am trying to compute the coefficient of a polynomial as follows:
However, Maple complains that it cannot compute the coefficient, which is clearly not zero. Does anyone have any suggestions? I wonder under what circumstances would Maple decide that it cannot compute the coefficient of a polynomial? (I tried a simpler expression involving r^(-1) and it worked.) It is utterly important that Maple picked up the coefficient in my algorithm. Thank you for your insight.
