  • SAL PLEAAASE do a video on coplanarity because I just cant find anything online thats simple!

  • wait i'm confused, He multiplied the 1/ LENGTH of V, which as he said is just a number, with the VECTOR V, and then cancelled them out to get 1. How can you cancel out the length of something with a vector?

  • @zinizterz He was saying 1/ ||v|| multiplied with vector v will make that vector's length 1. Unless I'm confused about your question, in which case, send me a message or something and I'll try to clear it up.

  • thanks sal. linear algebra rocks!
