# Vector division or inversion

How do you get a vector to the power of negative one?

I.E. : V ^ (-1)?

Or inversion if that's what it's called?

Thank you.

I have never seen "division", or for that matter powers or products defined for vectors. Perhaps if you told us where you saw that and the situtation involved, we could say.

In edit: It has been pointed out to me that I forgot the "cross product" of vectors- but that is only defined for three dimensional vectors and still does not have multiplicative inverses defined.

I see that it is more involved than I was hoping.

I followed the thread, and the other person is,

or was, having the same difficulty as I am or were.

Thanks :). Jasper.
