Description

MATH 1B03: Linear Algebra I

Instructor(s): N Anvari. 

Prerequisites: One of Grade 12 Calculus and Vectors U, Grade 12 Geometry and Discrete U, MATH 1F03

Antirequisites: MATH 1ZC3

Course Overview

An introduction to linear algebra. This course discusses matrices and their properties, including determinants, eigenvectors/eigenvalues, diagonalization, and invertibility. Vector spaces are also defined and discussed more generally. This course reveals some of the ways in which matrices are used by computers to effectively manipulate data, and is relevant in many upper-year courses.

3 lectures and 1 tutorial per week (1 hour each).

Required Materials

Elementary Linear Algebra by Anton & Rorres

Casio fx991-MS/MS PLUS calculator

MATLAB- Computer Software

Course Content

The course loosely was divided into three sections i) an introduction to matrices and their basic properties ii) further properties and iii) generalizing vector spaces. This third section acts as a basis for further studies in Linear Algebra. There is a test (midterm) after each of the first two sections and an exam at the end of the course. 

Evaluation

EVAL 1: Tests 40% (20% each)

EVAL 2: Labs 10% (2% each)

EVAL 3: Assignments (2% each)

EVAL 4: Final Exam 40%

Other Useful Information

There is a large amount of theory within this course and is traditionally a student's first experience with a largely theory course. Understanding definitions and theory in conjuction with practice problems is important in doing well in the course.
