The anonymous sorted grades for the combined homeworks scaled to 25,
hw_sorted_grades.txt.
The webassign portion is 332 points.
The portion submitted on paper to me is worth 23 points for Homework 3
and 45 points for Homework 4, plus 5 bonus points for Homework 2, hence
a possible total of 405/400 (times 25 for the 25% portion of the grade).
I have one paper Homework 4 without a name.
-
30 of you received 5% towards your final grade for missing
no more than 2 classes unexcused.

Correction to what I said in class: the vector space dimension of
the eigenspace (geometric multiplicity) is not always a factor
of the algebraic multiplicity
of the corresponding eigenvalue. An example is
A:=Matrix(3,3,[[0,0,1],[0,0,0],[0,0,0]]); The eigenvalue 0 has
algebraic multiplicity 3, but the dimension of the nullspace
of 0 I_3 - A is 2.
