A few Maple notes. To generate the random matrices and check their determinants in Maple you may use the commands
matel:= ran(0..1);
for j from 1 to 100 do
  M:=matrix(6,6,[ seq(matel(),i=1..36) ]):
  y[j] := det(M):
od:
add( abs(signum(y[j])),j=1..100);
This may be useful for exercise 4 on page 107. (Note that the book contains the relevant MATLAB code,)

There will be three in-class exams worth 16% each.
The final exam will be worth 32%.
