 :([Coming in three+ years later] A triplet like (1,2,3) can be treated as a vector in 3-space. Consider it the termination of a line segment extending out from the origin (0,0,0). You now have a direction (the way the segment points) and a magnitude (its length)--that is, a vector. [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 03:41, 18 November 2023 (UTC)
