Question:
Let
(a) Graph f.
(b) Find fx(x, y) and fy(x, y) when (x, y) ≠ (0, 0).
(c) Find fx(0, 0) and fy(0, 0) using Equations 2 and 3.
(d) Show that fxy(0, 0) = −1 and fyx(0, 0) = 1.
(e) Does the result of part (d) contradict Clairaut’s Theorem? Use graphs of fxy and fyx to illustrate your answer.
