By using polyder() and polyint() how we can solve following problems

let p=[3 5 6 2 1] %polynomial of degree 4 (1) How can i find 3rd order derivative(i.e. any order using polyder)?

(2) let another p=[1 1 2] %polynomial of degree 2 how find (a) its integration within given limits let [0 5] (b) its double integration within given range suppose anything
