Please provide the full solution, thanks

Compute Vf. OK , (i) f(x, y, z) = y2 + 22 with V= ax ay az a 1 2 + ed + ez I ep az (ii) f(p, 4, z) = p2 sin?($) + 22 with V= ap 1 0 er + ee + r sin(0) ad (iii) f(r, 0, $) = 12 -r2 sin? (0) cos2 () with V= ar r 20 (iv) Optional: Confirm that the functions and gradients computed in (i)-(iii) are equivalent
