                             Day 16.R


    1.  RAT on cross product

        A.  Find cross product of two given vectors.

        B.  Verify that your result is orthogonal to the two 
        vectors. 

    2.  Allow time for questions and discussion before and after 
    the RAT on three-dimensional vectors, determinants, and cross 
    products. 
NO DEMAND FOR THIS, SINCE IT WAS COVERED IN RECITATION THE DAY 
BEFORE.

    3.  Jigsaw:  Explain your problem to your new team.  Call 
    attention to any hard or interesting problems that deserve 
    attention by the whole class.
THE CIRCULAR LAKE PROBLEM PROVED VERY CHALLENGING TO EVERYONE, 
INCLUDING ME -- COMMITTED TO PRESENTING A SOLUTION NEXT TIME.
