What is Vector Inversion and How Does It Differ from Vector Division?

Click For Summary

Discussion Overview

The discussion revolves around the concept of vector inversion and its distinction from vector division. Participants explore the definitions and mathematical operations related to vectors, particularly focusing on the idea of raising a vector to a negative power.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about how to express a vector raised to the power of negative one, suggesting a concept of vector inversion.
  • Another participant expresses skepticism about the existence of division or powers for vectors, noting that these operations are not commonly defined in vector mathematics.
  • A third participant provides a link to a related thread, indicating that there may be additional insights or discussions on the topic.
  • A later reply reflects on the complexity of the topic, acknowledging shared difficulties with understanding vector inversion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definitions or applicability of vector inversion and division, with some expressing uncertainty and others questioning the validity of these concepts.

Contextual Notes

The discussion highlights limitations in the definitions of vector operations, particularly regarding the absence of multiplicative inverses for vectors and the specific conditions under which certain operations, like the cross product, are defined.

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.
