Example: For the polynomial "poly = x + 3 x^2 + 2 x^3 - 2 y +6 x y - 5 x^2 y + 8 x y^2 - 4 x^2 y^2" the function Collect[poly,y] gives "x + 3 x^2 +2 x^3 + (-2 +6 x - 5 x^2) y + (8 x - 4 x^2) y^2". How do I select the individual coefficients of y^n , n = 0,1,2 to individually work on them, like for example to take the derivative of the coefficient of y^2?
