MATH 32A Lecture Notes - Lecture 1: Pythagorean Theorem, Multivariable Calculus, Scalar Multiplication
Document Summary
This is chapter 13 in the textbook multivariable calculus . A vector is a directed line segment. This is usually represented as an arrow in 2-d or 3-d space from one point to another. Can draw an arrow on a graph from coordinates (2,1) to (4,4), that is a vector. This vector is denoted as v, with an arrow pointing to the right on top of the v. This is the notation for a vector in this course. A vector can be denoted as any letter, but usually v. but it must have an arrow pointing to the right on top of it to indicate it"s a vector. The vector from point p to point q is written as pq, and putting one arrow pointing to the right above both letters. We only care about the direction and length of the vector.
