Evaluate R C y sin z dx + (2 y + x sin z ) dy + xy cos z dz where C is the curve param- eterized by r ( t ) = cos( πt ) i + e t j + πt 3 / 2 k , 0 t 1. [15] 2. Evaluate R C ( xy + z ) ds where C is the curve parameterized by r ( t ) = t i + 3 t j + (2 t + 3) k , 0 t 1 . [15] 3. Evaluate R C ( x 2 + 2 y ) dx + sin( y 3 ) dy where C is the curve shown below consisting of the part of the x -axis between ( - 1 , 0) and (1 , 0) and the part of the parabola y = 1 - x 2 above the x axis. [20] 4. Let D be the solid region bounded below by the cone z = p x 2 + y 2 and bounded above by the plane z = 3. Evaluate R R Σ F · n dS
