Consider the functions z = -3 e* In y, x = ln (u cos v), and y = u sin v. əz əz (a) Express and as functions of u and v both by using the Chain Rule and by expressing z directly in terms of u and v before differentiating. ди Əv əz (b) Evaluate and du dz Əv at (u, v) = 5, (a) Find each partial derivative needed to use the Chain Rule to find əz ди əz dx 𐐀x ди əz ду dy ди
