Course Description

Description

Linear Algebra is an online and course equivalent to a first-year college linear algebra course. This course covers the entire syllabus from the Johns Hopkins one-semester, in-person Linear Algebra course, plus several additional topics. Online interactives and assignments help to reinforce concepts taught in the class. Projects covering advanced applications will introduce students to mathematical typesetting with LaTeX. Online course materials supplement the required textbook.

Online course materials, such as videos, notes, interactive webpages, and practice problems with solutions, are provided for the student. Students are expected to watch videos and review notes regularly. Each student is assigned to a CTY instructor to help them during their course.

In this course, participation in forums and synchronous online virtual sessions are required as part of the final grade. Discussion forums are located within the course where students will be required to respond to a given prompt and then comment on responses by other students. Online sessions, led by a CTY instructor, are held in Adobe Connect, which allows for video, voice, text, screen sharing, and whiteboard interaction. 

Students can contact their instructors via email with questions or concerns at any time. Live one-on-one online review sessions can be scheduled as well, to prepare for the graded assessments, which include quizzes, homework, projects, unit exams, and a cumulative final.

The textbook must be purchased separately.

Topics include:

  • Linear equations
  • Matrix algebra
  • Determinants
  • Vector spaces
  • Eigenvalues
  • Orthogonality
  • Least squares
  • Symmetric matrices
  • Quadratic forms
