Multivariable Calculus Unit 1 Lecture 01: Welcome to (x,y,z) space R3

Welcome to Lecture 1 of Multivariable Calculus! This video is about (x,y) and (x,y,z) space. We look at the layout of R3, points, the distance formula, circles, spheres, and circular cylinders. In this video we explore the jump from single-variable calculus to multivariable calculus: - R² (2D space) vs R³ (3D space) - Equations of lines, planes, circles, and spheres - Octants in R³ - Distance formula and its applications This course is designed for students taking Calculus III.
