Determine whether each of the following is Always True,
Sometimes True, or Always False. If the statement is Always True or
Always False, provide a brief justification. If the statement is
Sometimes True, provide an example of a series that makes it true
and an example of a series that makes it false. In the following,
{a_n}∞n=1 is a sequence and {s_n}∞n=1 refers to the corresponding
sequence of partial sums.

67. Explain why or why not Determine whether the following state- ments are true and give an explanation or counterexample. a. If f(x, y) x2 + y2 - 10, then Vf(x, y) = 2x + 2y b. Because the gradient gives the direction of maximum increase of a function, the gradient is always positive. c. The gradient of f(x, y, z) = 1 + xyz has four components d. If f(x, y, z) = 4, then Vf = 0
