2) Find the work of F = (x² - y² - 1, xy) on the semi-circle of radius 2 centered at the origin starting at (2,0) and ending at (-2,0) oriented counter-clockwise. Use the vector field grapher shown in class and cut and paste the vector field here. Before you calculate the circulation do you expect your answer to be positive, negative, or zero?
