machine ?

9. Some Basics

10. Vector (x, y)

11. Vector 1 (x1, y1)
Vector 2 (x2, y2)

12. Vector 1 (x1, y1)
Vector 2 (x2, y2)
Can a machine calculate distance between these?

13. Vector 1 (x1, y1)
Vector 2 (x2, y2)
Can a machine calculate distance between these?
(0,0)

14. Vector 1 (x1, y1)
Vector 2 (x2, y2)
(x2-x1)
(y2-y1)
(0,0)
Can a machine calculate distance between these?

15. Vector 1 (x1, y1)
Vector 2 (x2, y2)
(x2-x1)
(y2-y1)
d2 = (x2-x1)2 + (y2-y1)2)
(0,0)
Distance between vectors

16. Vector 1 (a1, b1, ………,n1 )
Vector 2 (a2, b2, ……….., n2)
d2 = (a2-a1)2 + (b2-b1)2 + ……+ + (n2-n1)2)
In higher dimensions:
