How to find the shortest distance between points on lines - Vectors in 3D

A tutorial on how to find the shortest distance from one point on a line to another line.
This tutorial covers finding the angle between two lines, magnitudes and the dot product, all in 3 dimensional vectors.

You're videos are very helpful! I'm sitting AQA C4 tomorrow morning and I desperately needed help on Vectors. I'm very grateful mate, thanks a lot :)

OMG this is so simple I cannot believe that I didn't see the big picture until just now!!!

Thanks

[@hiralpethad9011]

very good lecture, would like to see more examples

[@deposition2223]

why couldn't we just simply utilize the method given in the previous video? we had a point and a line so why go through all the trig work?

[@marcusharton5463]

Just to use the opportunity to show how to do those kind of problems, as they might also ask for the angle between, use the dot product, etc.
