SOLVED: The figure shows level curves of a function f(x,y). Draw gradient vectors at P and Q. Is Vf(P) longer than, shorter than, or the same length as Vf(Q)? shorter than.(b) If C is the line segment from P to Q, then kvf-d =.(c) If C is any piecewise-smooth path from T to Q, then ∮ Vf .dr =.(d) If C is any piecewise-smooth path from S to P, then ∮ Vf .dr =.If C is any piecewise-smooth closed path from P to Q to T to S to P, then ∮ Vf .dr =.Click on graph to enlarge.
