@Markiyan Hirnyk Is this command appropriate for checking Independence or dependence of some polynomials with parametric coefficients?

@Markiyan Hirnyk  This is derivative of the polynomials w.r.t. the variable x. What is results if we use
Wronskian([x^2+y^2, x^2+y, y^2-y], y, 'determinant')?

@Markiyan Hirnyk For example if f=x^3+y^3+xy-y  and g1=y+x^2 , g2=y^2-y then f=(x)g1+(y-1)g2 and this is obvious that x , y-1 are not in field R!!!

@Markiyan Hirnyk But this is nice for this example. for another example we can not decide whether a polynomial is a linear combination of some polynomials by Grobner basis. Since of, the coefficient must be in field K and in normalform command coefficient are polynomial!!

@Carl Love Thanks very much for this good help. Yes. ColumnDimension is better in my procedure.

@Carl Love If I want to use from EliminationIdeal command, from this time, at the first I have to paste the code that Roman gave in my Maple sheet. Is this true?
