Course Learning Outcomes:

  • Construct direct and indirect proofs and proofs by induction and determine the appropriateness of each type in a particular setting. Analyze and critique proofs with respect to logic and correctness, and prove conjectures
  • Learn to construct proofs that are not only mathematically correct but also clearly written, convincing, readable, notationally consistent, and grammatically correct,
  • Apply the logical structure of various proof techniques, proof types, and counterexamples and work symbolically with connectives and quantifiers,
  • Perform set operations on finite and infinite collections of sets and be familiar with properties of set operations and different cardinalities for infinite sets,
  • Work with relations and functions, including surjections, injections, inverses, and bijections, equivalence relations, and equivalence classes,
  • Learn to work with εδ definitions and proofs involving limits at a point for polynomials, rational functions, as well as transcendental functions that do not have a limit at a point,

Course Content to be Covered

Syllabus: As a rough guide, we will cover most Chapters from the following:

  • Chapter 1: Sets
  • Chapter 2: Logic
  • Chapter 4: Direct Proof
  • Chapter 5: Contrapositive Proof
  • Chapter 6: Proof by Contradiction
  • Chapter 7: Proving Non-Conditional Statements
  • Chapter 8: Proofs Involving Sets
  • Chapter 9: Disproof
  • Chapter 10: Mathematical Induction
  • Chapter 11: Relations
  • Chapter 12: Functions
  • Chapter 13: Cardinality of Sets
  • Epsilon-Delta Proofs

General: A typical class will begin with some problems for the previous class to test comprehension. Students will be expected to work with one another on these problems and, on occasion, present solutions. Then, I will introduce topics and examples of proof techniques from the text. It is important to understand what goes on in class each day. This means being present and being prepared for every class, first by reading the textbook and second by making a serious effort to do the homework.

It is encouraged that you work together both on reviewing the material and doing the homework. However, this is not an excuse for copying some one else’s work. Every student is expected to turn in their own, original work.

Academic Integrity:

Hunter College regards acts of academic dishonesty (e.g., plagiarism, cheating on examinations, obtaining unfair advantage, and falsification of records and official documents) as serious offenses against the values of intellectual honesty. The College is committed to enforcing the CUNY Policy on Academic Integrity and will pursue cases of academic dishonesty according to the Hunter College Academic Integrity Procedures.

Disabilities: If you have a disability that you believe requires special accommodations: In compliance with the American Disability Act of 1990 (ADA) and with Section 504 of the Rehabilitation Act of 1973, Hunter College is committed to ensuring educational parity and accommodations for all students with documented disabilities and/or medical conditions. It is recommended that all students with documented disabilities (Emotional, Medical, Physical and/or Learning) consult the Office of AccessABILITY located in Room E1124 to secure necessary academic accommodations.
