Question

Determine a vector perpendicular to u=[6,-5]

Answer 1

i think ur vector \[u=6i-5j\]

Answer 2

now i wanna find out a vector which will b perpendicular to ur given vector u

Answer 3

let the perpendicular vector is \[v\]

Answer 4

So change to unit vectors
Then?

Answer 5

\[v=5i+6j\]

Answer 6

Why would it flip?
Is it because you made v=0 then just moved it over?

Answer 7

Is there a rule for that?

Answer 8

ya

Answer 9

if u do dot product of \[u\] and \[v\] then u will get 0

Answer 10

Oh. Because it has to be cos90, which is = to 0
Okay

Answer 11
