Sec. 7, last half of 10.3, due March 14, 2012

The rest of the section appears to have already been covered in class.  It was taken up with the examples proving that (0,1) was numerically equivalent to the set of real numbers.  The main thing that would be beneficial would be to do as many examples as possible during class time with proofs typical of sections 10.2 and 10.3.
