[18 Nov 2019] Second prelim stats: median: 83, median 81.9, stddev 13.7, range: 32 - 100, rough letter grades: >= 90 A, >= 78 B, >= 65 C.
[18 Nov 2019] HW10 has been posted. Caution: the due date is not the usual: it is Monday, Nov 25 in class. Office hours this week have also been
changed accordingly: Beihui Yuan: Thursday 1:30 - 3:30, Mike Stillman: Friday, 3 - 5 pm. Usual places!
[10 Nov 2019] Here are some previous prelim's for practice for prelim2.
practiceA (fall 2015)
practiceB (spring 2017)
and practiceC (2012)
. We will discuss the
answers on Wednesday in class. Some problems are not relevant for us
Fall 2015 prelim2, ignore: TF(a,c,e), Question 1. Spring 2017 prelim2: all problems are OK.
2012 problems: ignore Question 2, Question 4. Also, the notation here is not our standard:
N(T) means the kernel of T, S(v1, ...) means the span of the given vectors. Renni product: is a made up term!
Note that this was a take home exam, so is longer
and more involved than what we will have. Still, any specific problem would be reasonable on
our exam. As usual, these practice problems do not cover everything that we have done. You might also look at all the T/F questions in
Friendberg, Insel and Spence (1st problem of each section, usually).
[10 Nov 2019] Problems 3(c) on HW9 has a typo! The first integral should be squared: HW9 has
been updated to fix this typo.

tell Prof. Stillman about it by Wed, Oct 30.

[10 Oct 2019] Here are some basic answers (not all proofs are done out
in full, T/F don't have explanations, but hopefully it will still be
useful. practice prelim solutions A,B,C
[4 Oct 2019] Here are some previous prelim's to try.
. We will discuss the answers on Wednesday in class.
Some problems are
not relevant for us (i.e. ignore practiceB: TF(b,c,d), question 3 (in
question 2, they assume you know the def of the dual vector space, which we will not assume).
practiceC: short answer(d), short answer (e, part iv, v), and question 3).
