Grader's comments

HW1:

2 things I came across was most ppl forgot to write
x(not=)0 and mod(y)< or = 1  for question 6 (ex 2.2)
and for q.5 of ex2.2,
  x(not=) -1 and y(not=)0.
Most of them did not get the correct answer for q.19.

HW4:

Each question is 2 points except for
Ex. 4.2 - #22, Ex.3.6 - #1 ,#3, Ex.4.3 - #2 which are one point each.

HW5:

All the questions were awarded 2 points except #1,3 in
section 5.1 which were awarded 1 point each.

HW6:

All questions were 2 points each
except for Section 5.3 - 5,6,7,8 which were 1 point each.

HW8:
All questions were 2 points except Sec.6.1 #26 and Sec.6.2 #21.
 One thing I noticed was that everyone made mistakes
 in the (d) part of the #26 in Sec. 6.1. -> the gamma function problem.

HW9:
All questions were awarded 2 points other than
Section 6.3 - #8, #11 which were awarded one point each.

HW10:
The points allocated for each question are as follows.
7.5 : 16 -> 6
7.6 : 2  -> 6
7.8 : 9  -> 8
Thus, all the papers were graded out of 20.

HW11:
All questions were graded out of 2 points except Sec.10.4 : #2, #3
which were graded out of 1 point each.
