hi mr jack, why do you put vector for L1 (2 1 1) and not L2 (-6 -3 -3) in 3:34

[@TLMaths]

It wouldn't matter which one you use

[@kiritoakz]

thank youuuuuuuuu

[@SadikKhan-wt8cs]

Thanks!!!

[@michaelchapisa3709]

Thank you for the video, bt why cant we use both of the position vectors of both lines

[@ashtongrimmett2456]

Its another way of doing it using simultaneous.

Because that may not be the shortest distance.
