Question: If you did Exercise 60, you know that the function is continuous at (0, 0). Find xy (0, 0) and yx (0, 0).

If you did Exercise 60, you know that the functionf(x, y) x - y xy x + y 0, (x, y)


is continuous at (0, 0). Find ƒxy(0, 0) and ƒyx(0, 0).= (0, 0) (x, y) = (0, 0)



Data from Exercise 60


Define ƒ(0, 0) in a way that extendsimage


to be continuous at the origin.

f(x, y) x - y xy x + y 0, (x, y) = (0, 0) (x, y) = (0, 0)
