From Example Problems

Since the integration is performed in xy-plane, we have The path of integration C consists of the straight line OA and AB. Now, we have

= --(1)

The equation of the straight line AB is i.e

Therefore,on OA,y=0,dy=0 and x varies from 0 to 2, and on AB, and x varies from 2 to 3. Then from the equation (1),

=
