The region R is shown in Figure Q5. The vector field F is given by F = y a, + 3xyay 9. 2. 3. y = 9-x2 1. 3. Figure Q5 i. Evaluate 6,F dl using close line integral. ii. Verify the answer from Q4.b(i) using Stokes's theorem. The region R is shown in Figure Q5. The vector field F is given by F = y a, + 3xyay 9. 2. 3. y = 9-x2 1. 3. Figure Q5 i.
