MAT 300

Current Grade. Enter the last 4 digits of your affiliate id:

The score checker will now compute your current average, and also compute what you need to average from now to the end of the course to get into different grade ranges. The results of these computations are unofficial. You should do the computations yourself to be sure.

When thinking about how much to study for the remaining exams, keep the following in mind. Say you need to average 40% to get the grade you want. If you know 40% of the material, then taking many exams, your average score would be around 40%. So, roughly half of the time you fall short. So, it is a bad idea to try to just barely make it into a particular grade range.

  • 4/19 Here are solutions for Test 2.
  • 4/15 The last day of class is reserved for a question/answer related to the final, so bring questions.
  • 4/2 Test 2 is coming up in about 2 weeks. It will cover material starting with ordered pairs and ends with the homework due on 4/10. This includes
    • ordered pairs and Cartesian products
    • relations, and general operations on them (inverse and composition)
    • properties of relations (reflexive, symmetric, antisymmetric, and transitive)
    • partial orders
    • functions, and their properties (injective, surjective, bijective, inverse functions)
    • equivalence relations, partitions, and complete sets of representatives
    • well-defined operations and functions
  • 3/8 Here are solutions for Test 1. Scores can be access above. The high score was 90, and the median was 67.
  • 2/13 Test 1 is in just over 2 weeks. It will cover material from the start of the course through power sets. In particular, it covers
    • making truth tables, and determining logical equivalence
    • negating statements with quantifiers; stating the converse and contrapositive of an if-then statement
    • direct proofs
    • counterexamples for disproof
    • proof by contradiction
    • proofs with cases, including bootstrapping
    • mathematical induction
    • sets: union, intersection, set difference, set complement, subset, set equality, the empty set, and power sets
    It does not cover ordered pairs or products of sets.
  • 2/11 Office hours are cancelled for February 14 while I am covering a class for another faculty member.
  • 1/24 Here is an updated list of the order in which we have covered things/will cover them: 2.1, 2.3, inequalities, 3.1, 3.2, 3.4, 3.3, (3.5 and 3.6), 2.2, 4.1-4.4, 5.1-5.5. The sections in parentheses should be read, but they have little to no actual material in them.
  • 1/15 Expect a quiz (involving truth tables) on Thursday of this week.
  • 1/11 In the book, we just covered section 2.1 and will do section 2.3 next.
  • 1/5 Handout on inequalities.
  • 12/29 Office hours are cancelled for January 10 and 11 while I am at a conference.
  • About this course
    This is a course in how to read and write mathematical proofs. This involves
    • Formal logic
    • Use of quantifiers and variables
    • Basic proof techniques
    We will practice our proof writing primarily with set theory, which underlies many subjects in math.
  • Exams:
    • Test 1: March 1
    • Test 2: April 19
    • Final: May 3
  • Office hours: Tuesdays and Thursdays 10:30-11:20, Wednesdays 1:00-1:50, and by appointment.
  • ASU Student Code of Conduct, especially F1 and G.
  • ASU policy on rescheduling final exams: ACD 304-01
  • ASU policy on missed classes.
