+xy k and s is that part of the surface of the example-23: evaluate fhds, where f = yzî +zx sphere x+y +2 =l while lies in the first octant.

here is the solution.. only Remember this Gauss divergence therorm...

whenever you are asked with such questions. The first step, you should do is to check whether the use of Gauss divergence will help you or not?. yess in most of the cases it helps....

solution is done with the help of Gauss divergence theorem.hope it will help you.
