Question: Use a graph of the vector field F and the curve C to guess whether the line integral of F over C is positive, negative,

Use a graph of the vector field F and the curve C to guess whether the line integral of F over C is positive, negative, or zero. Then evaluate the line integral.

F(x, y) = (x - y) i + xy j, C is the arc of the circle x2 + y2 = 4 traversed counterclockwise from (2, 0) to (0, -2)
