Overview. Matrices, vectors, vector spaces, transformations. Covers all topics in a first year college linear algebra course. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

So we have U1, which is a unit vector. It has length 1. So that is U1. V1 and V2 are linearly independent, that's by definition of a basis. So you can't represent V2 as a linear multiple or linear combination of V1. Likewise, you can't represent V2 as a linear combination of U1 because U1 is a linear combination of U1. Preview

Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Khan Academy.

Practice Exercises for Linear Algebra. I've been on Khan Academy for over 3 years now, and this site has saved my ass more than once. Just last year I was struggling with calculus before a big exam that might have seen me out of university early, but I watched these videos on Khan Academy and did the exercises and I passed (after maybe a week Preview

Khan academy and 3blue1brown are very good supplementary resources. They should never be used by themselves. You need an actual linear algebra book to go through too. Furthermore, if you want to learn more mathematical linear algebra (vector spaces, subspaces, etc.) then khan academy is completely insufficient. 87. Preview

posted on October 25, 2012. News. Software developer Stephanie Chang has just launched the very first Khan Academy exercises in Linear Algebra, the college-level topic involving vectors and matrices: Matrix dimensions. Matrix addition and subtraction. Scalar matrix multiplication. Defined and undefined matrix operations. Preview

These linear algebra lecture notes are designed to be presented as twenty ve, fty minute lectures suitable for sophomores likely to use the material for applications but still requiring a solid foundation in this fundamental branch Preview

Khan Academy's linear algebra lecture series provides a thorough introduction to linear algebra from the basics of vectors and matrices to projections into lower dimensional spaces, eigenvectors and eigenvalues. Khan has an impressive amount of knowledge and manages to be engaging with his voice-overs despite no actual face time.
