Name: Instructions. Show all work in the space provided. Indicate clearly if you continue on the back side, and write your name at the top of the scratch sheet if you will turn it in for grading. No books or notes are allowed, but a scientifc calculator is ok - though unnecessary . All work must be shown to receive credit. Please do not give decimal approximations For square roots, For trigonometric or exponential Functions, or For π . Maximum score = 100 points. . 1. (20) Evaluate the line integral R C xydx +( x y ) dy where C is the straight line segment from (2,0) to (3,2). 2. (20) ±ind a potential function f and use it to evaluate the path-independent integral Z (1 , 2) (0 , 0) ( y 2 +2 xy ) dx +( x 2 +2 xy + y ) dy 1
