Distance point and plane the Lagrange way 

In this video, I derive the formula for the distance between a point and a plane, but this time using Lagrange multipliers. This not only gives us a neater way of solving the problem, but also gives another illustration of the method of Lagrange multipliers. Enjoy!
Note: Check out this video if you want to see the classical version of finding the distance between a point and a plane: • Distance between a poi...
