# VC5.14

From Example Problems

Since the z-coordinates of each vertex of the given triangle is zero,hence the given triangle must lie in the xy-plane. In the present problem A is (1,0) and B is(1,1) and so the given triangle is OAB.Also,we have

--(1)

Equation of OB is i.e y=x.

Since here, n=k,so by Stokes'theorm, we have

=
