2 Consider the vector field G(z,y)-(1 + y, z). 61 a) Let Ci be the quarter cirele from (0,2) to (-2,0), EvaluateGdr. (Hist: Cr can be parameterized by r(t) = ã 2008(t), 2 sin(t)) for Ï/2 t r.) 6 b) Let Ca be the line segment from (0,2) to (2,0), Evaluate Gdr 2] c) From your answers from a) and b) is it possible that G is a conservative field? If so find the potential function
