Question:

Figure 6 shows the contour map for a hill 60 feet high, which we assume has equation z = ((x, y).
(a) A raindrop landing on the hill above point. A will reach the xy-plane at A( by following the path of steepest descent from A. Draw this path and use it to estimate A(.
(b) Do the same for point B.
(c) Estimate (x at C, (y at D, and Du( at E, where u = (i + j) / (2.
