Vectors | Chapter 1, Essence of linear algebra
Linear algebra’s foundation is the vector—understood in three closely related ways—and the two operations that make vectors useful: adding vectors...
Linear Algebra 11 | Matrices
Matrices enter linear algebra as the tool for solving systems of linear equations—problems that can involve many equations at once. A matrix is...
Abstract Linear Algebra 2 | Examples of Abstract Vector Spaces
Vector spaces don’t have to be made of arrows or coordinates—once addition and scalar multiplication obey the usual rules, almost any structured...
Linear Algebra 5 | Vector Space ℝn [dark version]
The core takeaway is that 3n (all n-tuples of real numbers) becomes a vector space once vector addition and scalar multiplication are defined...
Linear Algebra 6 | Linear Subspaces [dark version]
Linear subspaces are the subsets of a vector space where vector arithmetic never “escapes” the set: scaling and adding vectors from the subset always...
Linear Algebra 11 | Matrices [dark version]
Matrices enter linear algebra as a practical way to organize many numbers so they can later solve systems of linear equations. The core idea is...
