Problem 3: Multivariate calculus
For each of the following functions, (a) evaluate the function and
each of its partial derivatives at the points (1, 1), (2, 1), (1, 2), (10,5)
and (5, 10), and (b) draw a diagram with the level curve of the function
passing through the points (1,1) and (2, 2), and indicate the better-
than direction.
(i) f : R,→ R with f(x, z) = 2 I+3Vz.

(iii) f : R, → R with f(x, 2) = -(1/2)e-2 – (1/3)e-32.
++
(iv) f : R→ R with f(x, z) = 2 log(x) + 3 log(2).
