Several of you on Homework 4 wrote a Jacobi symbol (n/2) or (n/6), which is undefined for even
denominators. Instead, when applying quadratic reciprocity and keeping all
denominators odd, factor powers of 2 from the numerator of the Jacobi symbol,
((2^{e}·m)/b) = (2/b)^{e}· (m/b), where m is odd,
and (2/b) = (1)^{(b²1)/8}. Then you can apply quadratic reciprocity to (m/b).

Homework 4 is posted. Due last day of class.

The course web sites for
Spring 2010,
Spring 2009,
Spring 2008,
Spring 2007
and
Spring 2005
contain old homeworks, midsemester exams, and anonymous grade lists.

My office hours are listed on my
schedule.
