MATH 221 — Introduction to Linear Algebra

Matrix methods, vector spaces, eigenvalues, orthogonality, and mathematical abstraction.

Instructor: Ahmet Kaan Aydin

Term: Winter

Location: University of Maryland, Baltimore County

Course overview

This intensive course developed both computational proficiency and conceptual understanding in linear algebra. Students worked with matrix algorithms while also learning the language of vector spaces and the role of abstraction in scientific applications.

Topics

  • Systems of linear equations and row reduction
  • Matrices and matrix transformations
  • Linear independence, span, and bases
  • Null spaces, column spaces, rank, and invertibility
  • Determinants
  • Eigenvalues, eigenvectors, and diagonalization
  • Orthogonality, projections, and orthogonal bases
