Description: Introduced set notation (relatively) slowly and carefully. Introduced R^2, Z^2.
5:15 --- Did an example where a set is graphically presented as a collection of vectors in R^2.
11:08 --- Scalar multiplication of vectors, introduced linear combinations.
17:50 --- Introduced the word “basis” but didn’t carefully define it.
18:30 --- Introduced “the standard basis for R^2”, R^3, and R^4.
