Distance formulas

I've decided to release some selected (previously unlisted) lecture videos from my calculus classes to the public. I don't plan on doing this for many videos. The main reason I'm doing this is to see how well these lecture videos appear on my cell phone, and to see how many views I get and where the videos show up in search results. In this video, I show you how to compute all distances between points, lines, and planes in 2 and 3 dimensions. The emphasis is on geometric intuition and computational ease. You should already be familiar with the operations of the dot product and cross product to understand this video. 0:00 Introduction 0:46 Distance from a point to a line in 2 dimensions 10:32 Distance from a point to a line in 3 dimensions 16:40 Distance between parallel lines in 2 or 3 dimensions 24:12 Distance from a point to a plane 29:59 Distance between a line and a plane 34:00 Distance between parallel planes 37:36 Distance between skew lines #DistanceFormula
