                     HOMEWORK SUMMARY REPORT


  Assignment number: 12         
    
  Problem number: 7.6.10 

  Number of papers received: 4 

  Reviewing committee (Greek letter):  eta

  Comments:  All the papers received showed an understanding of the use of
polar coordinates to complete the integration.  One paper received
performed the integration using the hemisphere as well as the circle in
the x-y plane.  As a result the end answer was 0.  The problem only asked
for the integration over the hemisphere.

INSTRUCTOR'S COMMENT:  There are (at least) two different approaches to
this problem.  The chosen paper uses the "geometrical" viewpoint.  Some of
the others, and the one from fall '98, use the "algebraic" approach.
