# Linear Algebra Dimension

### This section contains a complete set of video lectures on linear algebra along with transcripts and related resource files.

**Linear algebra dimension**.
It parallels the combination of theory and applications in professor strangs textbook introduction to linear algebra.

Well lets try this course format.
In mathematics a set b of elements vectors in a vector space v is called a basis if every element of v may be written in a unique way as a finite linear combination of elements of bthe coefficients of this linear combination are referred to as components or coordinates on b of the vector.
Despite two linear algebra classes my knowledge consisted of matrices determinants eigen something something.

I will admit at first i loathed hoffman and kunze. Linear algebra matrix algebra homogeneous systems and vector subspaces basic notions determinants and eigenvalues diagonalization the exponential of a matrix applicationsreal symmetric matrices classification of conics and quadrics conics and the method of lagrange multipliers normal modes. I used this book in a linear algebra ii course. The elements of a basis are called basis vectors. This course covers matrix theory and linear algebra emphasizing topics useful in other disciplines such as physics economics and social sciences natural sciences and engineering.

All bases for v are of the same cardinality. The space obtained is called a quotient space and is denoted vn read v mod n or v by n. The dimension of a vector space v denoted dimv is the cardinality of its bases. To say that it was drastically different and more difficult from my first lin al textbook would be an understatement. In linear algebra the quotient of a vector space v by a subspace n is a vector space obtained by collapsing n to zero.

Equivalently b is a basis if its elements are. Name the course linear algebra but focus on things called matrices and vectors teach concepts like rowcolumn order with mnemonics instead.
