Linear Algebra
part 2 of 3

A total of almost 47 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 second of those three parts.

Prerequisites

  • Linear Algebra and Geometry 1 (systems of equations, matrices and determinants, vectors and their products, analytic geometry of lines and planes)
  • High-school and college mathematics (mainly arithmetics, some trigonometry, polynomials)
  • Some basic calculus (used in some examples)
  • Basic knowledge of complex numbers (used in an example)

    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 2

    Z
    How to solve problems in linear algebra and geometry (illustrated with 153 solved problems) and why these methods work.
    Z
    Linear combinations, linear dependence and independence in various vector spaces, and how to interpret them geometrically in R^2 and R^3.
    Z
    Row space, columns space and nullspace for matrices, and about usage of these concepts for solving various types of problems.
    Z
    How to compose linear transformations and how to compute their standard matrices in different bases; compute the kernel and the image for transformations.
    Z
    Work with various geometrical transformations in R^2 and R^3, be able to compute their matrices and explain how these transformations work.
    Z
    Transform any given basis for a subspace of R^n into an orthonormal basis of the same subspace with help of Gram-Schmidt Process.
    Z
    Determine whether a given matrix is diagonalizable or not, and perform its diagonalization if it is.
    Z
    Use diagonalization for problem solving involving computing the powers of square matrices, and motivate why this method works.
    Z
    Use Wronskian to determine whether a set of smooth functions is linearly independent or not; be able to compute Vandermonde determinant.
    Z
    Important concepts concerning vector spaces, such as basis, dimension, coordinates, and subspaces.
    Z
    How to recalculate coordinates from one basis to another, both with help of transition matrices and by solving systems of equations.
    Z
    Linear transformations: different ways of looking at them (as matrix transformations, as transformations preserving linear combinations).
    Z
    Understand the connection between matrices and linear transformations, and see various concepts in accordance with this connection.
    Z

    Z
    Understand the relationship between diagonalizability and dimensions of eigenspaces for a matrix.
    Z
    Be able to formulate and use The Invertible Matrix Theorem and recognise the situations which are suitable for the determinant test (and which are not).

    Great course, very carefully planned, well explained, and with a lot of good examples to ensure you understand the concepts and develop much needed intuition.
    And if you are coming back to refresh your memory on some of these topics, you will find the structure very helpful, too.

    The lectures are great with a good pace for accumulative assimilation Slides are also well-organised.

    Excellent explanations, illustrations and many solved problems of various levels of difficulty. The link between matrices and linear transformations is fascinating, beautifully shown with many pictures. The topics in this course are more difficult than in the first course, but Hania explains everything very clearly. She is an excellent teacher, and I can recommend all her courses to everybody who wants to understand mathematics (also visually) and learn how to solve problems.

    The logical simplicity of linear algebra could easily be disappointing had it not been for the effectiveness of linear computation. This course profiles the intuitive linear concepts in the computational direction, especially towards the algebra of matrices. The course obviously introduces new material, but it also much helps to practice the ideas and techniques previously acquired. Hania does an excellent job making complicated things look simple. A great course!

    Much like the Linear Algebra 1 course, this course contains very thorough explanations of the information with lots of worked examples. I'm only to lecture 37, but up to this point, material from the first course is more clear (particularly the subspaces material, for me). I really enjoy her teaching.

    This is a great course that thoroughly explores fundamental concepts in linear algebra. Not only does it contain plenty of worked examples to drill in concepts, but also contains sufficient proofs to motivate all results. It is rare to find a course that does both of these things so well.

    Hania is incredibly knowledgeable and has a talent for teaching difficult concepts in an easy-to-understand manner. Her ability to break down complex ideas into simpler parts makes learning both enjoyable and effective. Highly recommended for anyone looking to master challenging subjects!

    This course succeeds Hania's Linear Algebra and Geometry 1, and it is presented equally carefully. It centers on the core fact that the minimal generating sets for a linear space – the bases for the space – exist and are all of the same cardinality, and hence that the study of linear transformations, and then of the geometric objects that these transformations define, reduces to a calculus of matrices. Hania explains everything to perfection, always helping the logic with handy examples and geometric illustrations, smoothly and impressively detailed
