Office Hours

Held in RH410V. I will hold office hours on the week of Finals at:

Monday&Tuesday: 2:30 - 4:30 pm

Exam Date Reminders and Materials

Midterm Date: Monday May 1st, in Lecture.
Final Exam: Wednesday, June 14, 10:30-12:30pm, same place as Lecture.

General Rule of Thumb for Studying: Make sure you know definitions/theorems and mainly in this class, applying methods to solve equations. Make sure you can do, and moreover, understand the processes from lecture/discussion examples, homework problems, and quizzes. Feel free to email or ask questions on Piazza!!

For Final:
Prof. Smith's Practice Final Problems. Also, the midterm material may be useful, too. The Laplace Transform sheet that Professor Smith said he would include in the exam.
The Review Session Recording. Also, here are the solutions I've drafted to the practice final. Please let us know if you think you see any mistakes or have any questions!
Mistakes caught:
#7a: Plugged in s = -2 erroneously. We plug in s = -3, so C = -5/6.
#6c: Negative was wrongfully dropped in e^{-2t} sin(5t).

Here's a Summer 2016 Practice Final as well as its Solutions if you're interested in reading or practicing some more, since a lot of comments about the class were to see more solutions. Try to do it first, before reading the solutions! Keep in mind this exam may not be as reflective as Professor Smith's style, but it should be good practice. Also please let me know if you see any errors or have questions!

For Midterm:
Here's the professor's sample midterm. And, our Review Session Recording. Lastly, here are the sample midterm solutions from Prof. Smith.
(I added timestamps in the video desciption for what problems we did in the review session recording).

Notes and Resources

Laplace Transforms Cheatsheet. Added on this one: L{-tf(t)} = F ' (s). (Derivative of F(s))
Chapter 2.5 & Cauchy Euler Equations Worksheet.
Linear Dependence Example from Class.

*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).
