Question

in 2D vector the perpendicular of ( 2 3) is - ( 3 2)
What about in 3D vector?

Answer 1

\[\left(\begin{matrix}2 \\ 3\end{matrix}\right) become -\left(\begin{matrix}3 \\ 2\end{matrix}\right)\]
what about in 3D vector?

Answer 2

There are many perpendicular vectors.

Answer 3

so those inverses only apply at 2D vector? (as it contain only on perpendicular)

Answer 4

(2,3) is not a vector in 3 space

Answer 5

ok thanks
