Unit 1: Vectors: arrows and lists of numbers
About this unit
A vector is an arrow from the origin and the list of numbers that says how to reach its tip; adding and scaling work the same in both pictures.
By the end, you can: See a vector both as an arrow from the origin and as a list of coordinates, and add and scale vectors in either view.
