The path C shown below starts at the point (1, 1), passes through the point (1, 2), and then ends at the point (2, 2). Let F = y 2 i + 2xyj. (a) Compute R C F dr directly by parameterizing C. (b) Can R C F dr be computed using the fundamental theorem of conservative vector fields? If so, do the computation and verify your answer from part (a). If not, explain why not
