Question

Find two linearly independent vectors perpendicular to the vector v= <-8, 9, -3>

Answer 1

don't do that...this problem is too easy for that

Answer 2

that want L.I. vectors not orthogonal

Answer 3

The vectors need to be perpendicular (in other words orthogonal).

Answer 4

but they dont have to be orthogonal to each other

Answer 5

just L.I.

Answer 6

True

Answer 7

I could use <9,8,0>

and <0,3,9>

Answer 8

How do you get to that answer?

Answer 9

if v=<a,b,c> let w=<-b,a,0>

then v.w =a(-b)+b(a)+c0=0

Answer 10

thus \[\vec{v}\perp \vec{w}\]

Answer 11

okay. Thansk for your help.
