I think I've done it in some of the earlier linear algebra videos before I started doing a formal presentation of it. And I'm going to review it again in a few videos from now, but I think you understand how to …

Determining the equation for a plane in R3 using a point on the plane and a normal vector

A vector has both magnitude and direction. We use vectors to, for example, describe the velocity of moving objects. In this video, you'll learn how to write and draw vectors.

Showing that linear independence of pivot columns implies linear independence of the corresponding columns in the original equation. Created by Sal Khan.

In the last video I was a little formal in defining what Rn is, and what a vector is, and what vector addition or scalar multiplication is. In this video I want to kind of go back to basics and just give you a lot of …
