Dear all,

I am having some problems with the coeff() function in Maple13. I first defined a function "functie3";

> functie3;

When i try to obtain the coefficiënts from t2, t2^2, t2^3, t2^4 and the constants i always get the following error:

> coeff(functie3, t2, 2);

Error, unable to compute coeff

Could somebody help me out with this? Any help is greatly appreciated!!

Best Regards,

Sandro Iacovella
