Advanced Linear Algebra, Lecture 1.2: Spanning, independence, and bases
A subset S of a vector space X is a spanning set if every vector in X can be written as a linear combination of elements in S. It is linearly independent if there is only way to write the zero vector. Finally, it is a basis for X if it spans and is linearly independent. Loosely speaking, this means that it is "big enough to generate", but "not too big as to have redundancies". We introduce these concepts and prove some basic results, including that any two bases have the same size. This leads to the definition of the dimension of a vector space.
