6. In parts a and h of this problem, you are given a vector eld v. In each part, determine whether or not there is a function @(m, y, 2) such that v : VIP. If so, nd a function to. If notJ state why not. ALSO, in each part, calculate V x v and explain the result of the calculation in light of whether or not a potential g0 exists. a. v = {Elsiey, cos(z} sagey= ysin(z]) b. v : {1'2 y,$2y + 23,33,122 my)
