One paragraph, so you can see how it reads

MTH211 · UNIT 1 SETS AND FUNCTIONS

In this method, we list all the elements of the set: within braces. For instance, the collection of all positive divisors of 48 contains 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48 as its elements. S0 this set may be written as '{1, 2, 3, 4, 6, 8, 12, 16, 24, 48}.

What you should be able to do

  1. Define and apply set operations and relations.
  2. Explain and apply group theory concepts, including subgroups and Lagrange's Theorem.
  3. Define and identify integral domains and fields.
  4. Construct polynomial rings and apply the division algorithm.
  5. Determine irreducibility of polynomials using Eisenstein's criterion.
  6. Construct field extensions and identify prime fields.

Where it gets hard

The units students slow down on, and what makes each one heavy.

  • Module 1: Introduction

    Unit 1: Sets and Functions

    Understanding the formal definitions of reflexive, symmetric, and transitive relations and applying them to abstract examples requires careful attention to detail and logical reasoning.

  • Module 2: Advanced Topics

    Unit 1: The Basics

    Constructing the field of quotients involves understanding equivalence relations and performing operations on equivalence classes, which can be conceptually challenging.

  • Module 2: Advanced Topics

    Unit 2: Polynomial Rings

    The division algorithm for polynomials requires careful manipulation of algebraic expressions and understanding of polynomial degrees.

  • Module 2: Advanced Topics

    Unit 4: Irreducibility and Field Extensions

    Applying Eisenstein's criterion and understanding its theoretical basis requires a solid grasp of number theory and polynomial factorization.
