Linear Algebra

Resources

These linear algebra resources were created while I was TAing MATH 1850U at Ontario Tech University in the Fall 2023 term. They should still be applicable to other courses at Ontario Tech University, notably MATH 2050U, as well as to other students outside of Ontario Tech University who are studying a first course in linear algebra. These materials follow Elementary Linear Algebra by Howard Anton, 11e. For the more proof-based sections of the course, I may use Linear Algebra Done Wrong by Sergei Treil. Topics will be presented in the order of Anton. Those not using Anton or Treil will still find these resources helpful.
