Linear algebra change of basis. To say that it was drastically different and more difficult from my first lin al textbook would be an understatement. I used this book in a linear algebra ii course. Included area a review of exponents radicals polynomials as well as indepth discussions of solving equations linear quadratic absolute value exponential logarithm and inqualities polynomial rational absolute value functions definition notation evaluation inverse functions graphing. This note covers the following topics. Elements of a vector space may have various nature.
A first course in linear algebra is an introductory textbook designed for university sophomores and juniors. Name the course linear algebra but focus on things called matrices and vectors teach concepts like rowcolumn order with mnemonics instead. The first four axioms mean that v is an abelian group under addition. Here is a set of notes used by paul dawkins to teach his algebra course at lamar university. It parallels the combination of theory and applications in professor strangs textbook introduction to linear algebra.
We will begin our journey through linear algebra by defining and conceptualizing what a vector is rather than starting with matrices and matrix operations like in a more basic algebra course and defining some basic operations like addition subtraction and scalar multiplication. Typically such a student will have taken calculus but this is not a prerequisite. The book begins with systems of linear equations then covers matrix algebra before taking up finite dimensional vector spaces in full generality. For example they can be sequences functions polynomials or matriceslinear algebra is concerned with properties common to all vector spaces. 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.
Equivalently b is a basis if its elements are. I will admit at first i loathed hoffman and kunze. This section contains a complete set of video lectures on linear algebra along with transcripts and related resource files. The elements of a basis are called basis vectors.
