4. Consider the vector field / = (3+2mix - 3y with the following parameterized curve, C x( = ( sin(). yo =d cor). OSIS. a. Plot the vector field / along with the parameterized curve C. [2 pts] b. Judging from the plot in part a, will the value of the line integral positive or negative? How do you know based only the work in part a? [2 pts] C. Is Green's theorem appropriate to use in evaluating the line integral | F . of ? Why or why not? [2 pts] d. Calculate the line integral | Fear . [2 pts]
