Math1131 Linear Algebra Chapter 2 Problem 27 I

We find the parametric, point-normal and Cartesian forms for a plane in three dimensional space given a point it lies on and a ...

This solution shows how to calculate distances between points in 3d space and between points in 4d space. Presented by N J ...

Here we compute the angle between

Here we prove some fundamental properties of the dot product of vectors in three dimensional space. This is

Here we find the intersection (if any) of

Here we compute the area of a triangle from its three vertices in three dimensional space, using the idea of a cross product.

We find a parametric vector form of a plane given by a single Cartesian

In this video we prove a classical theorem of Varignon using vector methods. This is a harder

We discuss coordinate vectors and find the parametric vector form for a line through
