Linear Algebra
part 3 of 3

A total of 50 hours of lectures

This is an academic level course for university and college engineering. Due to its size, it is divided into three parts. This page describes the third of those three parts.

Level - Intermediate

  • High-school and college mathematics (mainly arithmetics, some trigonometry, polynomials)
  • Linear Algebra and Geometry 1 (systems of equations, matrices and determinants, vectors and their products, analytic geometry of lines and planes)
  • Linear Algebra and Geometry 2 (vector spaces, linear transformations, orthogonality, eigenvalues and eigenvectors, diagonalization)
  • Some basic calculus
    Basic knowledge of complex numbers (this course contains a short introduction to complex numbers)

Curriculum

Make sure that you check with your professor what parts of the course you will need for your exam. Such things vary from country to country, from university to university, and they can even vary from year to year at the same university.

Course Objectives & Outcomes for part 3

Z
How to solve problems in linear algebra and geometry (illustrated with 144 solved problems) and why these methods work.
Z
Use diagonalization of matrices for solving various problems from different branches of mathematics (ODE, dynamical systems).
Z
Work with geometric concepts as length (norm), distance, angles, and orthogonality in non-geometric setups.
Z
Orthogonal and orthonormal bases, and Gram-Schmidt process in various inner product spaces.
Z
Symmetric matrices and their properties; orthogonal diagonalization: how it is done and how to understand it geometrically.
Z
Quadratic forms and their connection to symmetric matrices: uniqueness of this correspondence and its consequences.
Z
Some concepts from abstract algebra: group, ring, field, and isomorphism; understand the concept of isomorphic vector spaces.
Z
Note: all the vector spaces discussed in this course are spaces over R (not over the field of complex numbers), and all our matrices have only real entries.
Z
Solve more advanced problems on eigendecomposition and orthogonality than in the second course.
Z
Inner product spaces different from R^n: space of continuous functions, spaces of polynomials, spaces of matrices.
Z
Pythagorean Theorem, Cauchy-Schwarz inequality, and triangle inequality in various inner product spaces.
Z
Min-max problems using Cauchy-Schwarz inequality, Best Approximation Theorem, least squares solutions.
Z
Positive/negative definite matrices, indefinite matrices; various methods of determining definiteness of matrices.
Z
Geometry of quadratic forms in two and three variables: conic sections and quadratic surfaces.
Z
Crowning of the course and a natural consequence of all the other topics: Singular Value Decomposition and pseudoinverses.

Professor Hania keeps me wanting to learn more from her! Great Experience!
Richard B.
Lecturer
This extends Hania's courses one and two with the same title, and it should be the most useful in terms of applications. It also is the hardest to present, if to follow the explicit style of the predecessors. Some abstraction is inevitable, handled carefully enough, but time is mostly spent explaining ideas and examining examples. The lectures are as easy to follow as any lectures could be, perhaps deceptively so, for some ideas are subtle. The students willing to listen and spend some time with the problems will be richly rewarded.

If you've already taken any of Hania's courses, then this will be beating a dead horse because you already know you can expect high quality.

Linear Algebra and Geometry 3 resumes right where part 2 leaves off, further building your intuition surrounding matrix diagonalization and eigenvectors. She touches on several useful auxiliary topics including an introduction to some abstract algebra concepts, solving systems of ODEs, difference equations, and more. As in my reviews for parts 1 and 2, I can't recommend this course enough.

Incredible lectures! So many important topics covered in such a clear and structured manner. The exercises were especially helpful in understanding the theory and how to use it. Really helpful. Highly recommend these lectures.

Simply amazing! I just finished the entire Linear Algebra trilogy and I have fallen in love with Math! Thanks Hania for your efforts.

This third course is definitely harder than the first and the second, but many illustrations and examples make it easy to follow and understand the content anyway. Hania explains all the details very clearly. The final part about SVD was really exciting. This is my 5th course by Hania and Martin that I've completed and I can recommend all of them.

The strength of this course is the many solved problems presented in various examples and from different angles.
Additionally a striking balance between theory and practical computations.
