Do question c please
Problem 1 (15 points) Find the work done by F over the curve in the direction of increasing t (a) F = xy + yj-y2k, and r(t) = t + t"j + t k, o t 1 (Ans: ½) (b) F-621+y21+12xk, )1+ (cost)1+(9k, ost (c) F = ãx,-z, 2y), curve C: from (0, 0, 0) straight to (1, 1, 0), then to (1, 1, 1), back to ) = (sin te cost ) + 2Ï (Ans: 0) (0, 0, 0). Is the field conservative? (Ans: 3/2)
