6. (10pt) (3.) Find a potential function for the conservative vector eld F(:1:,y, z) = (Zmyz + 3332, 2g + 1322, 23 22 + may). (b) Compute the vector l'me integral / F - air, where C is the straight line segment from (0,0, 0) to (0, 1, 2) C followed by the straight line segment from (0,1,2) to (1,1,1). (Hint: your answer from part (a) is helpful here.)
