Office Hours
Held in RH410V. I will hold office hours on:
Monday 3-4pm
Tuesday 2-3pm
Wednesday 3-4pm
Thursday 2-3pm
I may be a little late on Tu/Th office hours because of class from 1-1:50pm.
Exam Date Reminders and Materials
Midterm Date: Wednesday Feb 8, 10-10:50am in Lecture.
Final Exam: Monday Mar 20, 10:30am-12:30pm, same place as Lecture.
Practice Problems for final preparation. Removed the variation of parameters one.
Solutions for the Practice Problems. Included one of the Problem 3 1/2 solutions
and updated a fix for Problem 3.
Exercises for 6.2,6.3 for Final Prep: If the professor's list is a bit too exhaustive, see:
6.2 # 101-103; 6.3 # 2,9,101-104. (6.3.9 is similar to 6.3.104 and it is in the
practice problems too.)
Chapter 2.3, 2.5 Worksheet in preparation for the midterm.
Sample Midterm from Summer 2016 (NOT with Professor Guan though).
I hope it serves as good practice.
The Solutions to that sample midterm.
Notes and Resources
*0. Things not to do as a student. The author calls it a list of "badvice."
1. Trignometric Identities cheat sheet.
I really like this one because it gives brief derivations of them, too.
2. Integral Table reference for basic integrals.
** Please see a calculus book for review on integral techniques (For example, the Stewart book). **
Most if not all of these integrals can be done using those techniques, and you should/need to be able to do integrals by hand
in case of emergency and for exams.
3. Determinants: Cofactor Expansion: Notes and a video
on this. There's also a Diagonal method for 3x3s: Notes and
video. Computing determinants is necessary to get a matrix's characteristic polynomial.
4. Inverting larger matrices with row reduction
(recall from Linear Algebra). This is because there could be 3x3 matrices to invert apparently. We don't need this method for 2x2
matrices though, since we have a formula for that already.
Note: They slightly messed up the last example for 3 x 3. The last matrix is supposed to look like [ I | A ]
(they didn't write identity on the left, but the last row operation R1 = R1 - 2R2 does give identity on the left).
5. Academic Honesty. Know that you are really cheating yourself if you do so. (Updated).
Quizzes and Homeworks
Quizzes are on the assigned sections as in the syllabus. Homeworks are due a week after assigned.
Homeworks: HW 1 graded problems ,
Sec. 1.5 Solutions. **Disclaimer: These are solutions from an older version of
the Lebl Notes. They may or may not match the homework questions.
Also, I will not post homework solutions in general because the homeworks do not generally overlap.
HW 3 graded problems, HW 4 graded problems,
HW 5 graded problems
Extra Supplementary Exercises for Final Prep: 6.2 # 101-103; 6.3 # 2,9,101-104. (6.3.9 is similar to 6.3.104)
