Question

Consider the force field F defined by F(x,y)=(6xy-12,3x^2). Use the formula(16.2) to determine the work done by the force field F in moving object in an anti clockwise direction from the point(2,0) to (-2,0) along the cycle x^2+y^2=4 by applying (a) the method for evaluating a line integral that is described in ex 16.4.1
