Length 3d vector.

Apr 22, 2017 · @EelcoHoogendoorn You're completly right but this question is about length-3 lists vs. length-3 arrays and as the timings show this is in the regime where lists win (and arrays are not even close, they are 3-20 times slower). If the question were about "arrays of vectors" or length-100 vectors my answer would have been very different.

Assuming you want the shortest r possible: r is shortest when it is perpendicular to the Z Z -axis ends r ends at (0, 0, z) ( 0, 0, z)These are the magnitudes of a → and b → , so the dot product takes into account how long vectors are. The final factor is cos ( θ) , where θ is the angle between a → and b → . This tells us the dot product has to do with direction. Specifically, when θ = 0 , the two vectors point in exactly the same direction.
