Question

Find the vectors perpendiuclar to both of the given vectors.\[\left(\begin{matrix}8 \\ -3\\ 1\end{matrix}\right)and\left(\begin{matrix}7 \\ -2\\ 0\end{matrix}\right)\]

Answer 1

make a vector product of them and you got it

Answer 2

What's a vector product?

Answer 3

v X u =w

Answer 4

vector cross product .. thats the best way.

Answer 5

(2,7,5) is the answer

Answer 7

this is actualy a question related to the one you asked befor about the plane. You are looking here for the equation of the plane that contains bouth of this vectors, :)

Answer 8

I can't see that link very clearly, and don't understand it. Can you write it out in full here?

Answer 9

k, wait

Answer 10

I understand it. Don't worry :)

Answer 11

this is the way you calculate vector cross product. You will get a vector that is perpendicular to bouth of them
