I got stuck with the problem 3, i need your help, plz. thanks!!!!!!!
Problem 2 Let S be the portion of the paraboloid z x2 + y2 below the plane z 3. a) Parametrize S using cylindrical coordinates (include bounds for your new variables, r and θ) ement ds = Ili, à rell drda (ie the Jacobian) e area c) Find the surface area of S Problem3 Repeat problem 2a and 2b] using spherical coordinates instead. (Hint: In part b you should get that dS = cse®(d) cot(d)V4cot2(d) + 1 dod0)
