Class News:
- The lectures for the 1030 class on the dates of January 15, January 20, and January 22 will take place in EE 270. Our class will be temporarily merged with CSE 369 (Discrete for CS/EE). It is worth noting that finding 270 in EE is not trivial (or was non-trivial for me). Allow for some additional time if you are unaware of the complexities of this search.
- It seems moving our class to a room other than Univ 003 is nearly impossible with terrible options.
- Pset 1 and 2 have been posted.
- I updated the lecture notes with some links to some on-line resources.
- Our first in-class quiz will take place on February 3rd and will cover Pset 1. By cover, I mean I will pull 1-2 problems directly from the Pset and you can use your solutions to do the quiz. Each date when a Pset is due, we will have quizzes of an identical nature.
- Problem 4 (b) on Pset 2 has a typo. The series should sum to n/(2n+1) not 1/(2n+1).
- We will have our first mid-term on February 19 in class. The material will be from the first 6 lectures. I will post some additional information on the exam soon.
- I will be away on February 10, 12, 17, and 19. Britain Cox will serve as my replacement for those lectures. He will cover recursion, generating functions, and more on advanced counting.
- IMPORTANT: You will only require a writing utensil for the exam (pen or pencil). It is closed notes, closed books. You will not be able to use any reference material.
- Quiz 3 on Pset 3 will be on March 3.
- Mid-term 2: Covers probability theory and the arithmetic/algebra/congruence stuff.
- Mid-term 2: March 26. Same format as Mid-term 1.
- There is a quiz on March 24 on Pset 5.
- Mid-term 2 will have 6 problems. Problem 6 is two parts and is basic arithmetic.
- Solutions to Exam 2 posted. I want to reiterate that regardless of how you did on the exam (even if you collaborated), I believe in each of you and still hope very much for you to be successful not only in my course but in life. We all have bad days. We all make bad choices. These things don't define us as we are more than the choices we make. Each day we have a chance to improve as people. I am invested in each of you and that investment goes well beyond this course. You are amazing and I consider myself deeply fortunate to have such wonderful students.
- IMPORTANT: Problem set 6 has been posted and we will have a quiz on Pset 6 on April 6. I made the problem set short and simple (largely) as a result. Sorry for being mean!
- Pset 7 has been posted along with many picture scans and the Exam 2 stats.
- Pset 7, Problem 5 has a typo. The condition on distance is that d(a,b), d(a,c), and d(b,c) cannot all be equal for any triple of distinct vertices.
- IMPORTANT: Short review for mid-term 3 has been posted.
- IMPORTANT: There will be office hours Thursday AM this week. 800-1000 AM. No office hours 130-330 however.
- Added solutions to Exam 3.
- Our "final class" will be Saturday May 9th at 500 PM at the Pint. The Pint is located at the State/River intersection in West Lafayette.
