Question

How do i find the distance between these points:
(1,0,4) and (0,8,0) ??

Answer 1

subtract square add sqrt

Answer 2

its the same steps as finding the difference between any points in any vector space

Answer 3

(1,0,4)
-(0,8,0)
--------
1, -8,4 ; square em: 1, 64, 16

add em up 65 + 16 = 81

and sqrt it; sqrt(81) = 9

\[d=\sqrt{(x-xo)^2+(y-yo)^2+(z-zo)^2}\]

Answer 4

Oh dang. Pretty easy. Thank you. (:

Answer 5

youre welcome

Answer 6

\[\sqrt{(0-1)^2+(8-0)^2+(0-4)^2}\]
\[\sqrt{(-1)^2+(8)^2+(-4)^2}\]
\[\sqrt{1+64+16}\]
\[\sqrt{81}\]
9
