| ### Function Derivative ( elt-alg^pol/ord^pow f ) -> elt-alg^pol/ord^pow df ### Description Returns the derivative of f. ### Examples x_PA:= PolynomialAlgebra(FiniteField(5));; x_f:= Coerce(x_PA,X^2+2);; x_PSR:= PowerSeriesRing(FiniteField(5),x_f);; x_PSRx:= PolynomialAlgebra(x_PSR);; x_ff:= x_PSRx.1^2+Element(x_PSR,[1,2,3])*x_PSRx.1-2; Derivative(x_ff);
