1 : Let F = (2:1:It:(:|s(:1:2 + 33),? + 2y o::(;)s(.1:2 + 3.3)) and C be the curve joining (-1,-1) to (-1,0) by traveling on the curvms y = 2:3 from (-1,-1) to (0,0), then 1 y = 3:2 from (0,0) to (1,1) and nally on y = 1(3: + 1)(3: 3) from (1,1) to (-1,0). Evaluate / F - dr. 0 Hint: The direct computation can be very messy. Try an alternative approach
