Use Stokes' theorem to compute the circulation

F · dr

where F =

8xyz, 2y2z, 5yz

and C is the boundary of the portion of the plane

2x + 3y + z = 6

in the first octant. Here C is positively oriented with respect to the plane whose orientation is upward.

The boundary of a lamina consists of the semicircles

y =

sqrt(1 − x2)

and y =

sqrt(9 − x2)

together with the portions of the x-axis that join them. Find the center of mass of the lamina if the density at any point is inversely proportional to its distance from the origin.

1. [9 marks] Consider the boundary-value problem,
y′′ +2εy1/2 = 0, y(0) = 1,y(1) = 3/2.
Letting y = y0 + εy1 + ε2y2 + . . . , find y0 and y1 and hence y with error O(ε2).
