am looking over a solution to an answer and i dont get some things
Find the distance from the point A(1,-2,3) to the plane 2x-3x+6z-8=0
Then they picked a random point
However they also got a vector n=(2,-3,6)
That vector is included in
That turns out to be
(3,2,-3)*(2,-3,6) ALL OVER (2,-3,6)*(2,-3,6)
all times sqrt 2^2 +(-3)^2+6^2
My question is how did they get that point n?
Where could that have come from?
Thank you for your help
