A1. Let C be the curve in the my-plane that connects (1,2,0) to (0, 0, 0) along y = 2:52 and then (0, 0, 0) to (1, 1, 0) along y = :53. (a) By recognizing that F (as, y, z} = (25cc:er 29, 23:23\" 29,3325\" 21\") is a conservative vector eld, use the fundamental theorem of line integrals to evaluate Liz-div. (b) For those vector elds that are not conservative, sometimes we can separate them into the conserva tive and nonconservative parts, so that you can apply the fundamental theorem for the conservative part. Use this idea, along with part (a), to evaluate the following line integral: [Caraway + 2) do: + (2m2ez+2y) dy + ($282+2y + y) dz
