Cross Product of a Constant Vector

Click For Summary

Homework Help Overview

The discussion revolves around the concept of the cross product, specifically involving a constant vector and another vector. Participants are exploring the nature of the cross product and its application to different types of vectors.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the definition and properties of the cross product, questioning the relevance of the term "constant" in this context. There is mention of using a determinant to compute the cross product, and some participants express confusion about the relationship between the cross product and other vector operations like curl.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the original question and addressing misunderstandings. Some guidance has been offered regarding the nature of the cross product, but there is no clear consensus on the initial question posed.

Contextual Notes

There appears to be confusion regarding the terminology used, particularly the distinction between constant and variable vectors, as well as the relationship between the cross product and other vector operations. Participants are encouraged to clarify their understanding of these concepts.

Okay, now that my question has been cleared up, what is the cross product of a constant vector and a vector? Is there a formula?

To cross two vectors you can simply take the determinate of the matrix they make. As far as I know this method works for all constant and variable vectors which have a determinate that exist.

What do you mean by "the cross product of a constant vector and a vector"? The cross product is a product of two vectors. Whether "constant" or "variable" has nothing to do with the product.

And what question are you referring to with "now that my question has been cleared up"? This is exactly the question you asked in https://www.physicsforums.com/showthread.php?t=668424. If you did not understand the answers there, explain what you do not understand. Do not just start a new thread for exactly the same question!
 
Sorry if I have made SOME people upset. I wasn't really thinking about the math. Nevermind about this problem. A constant vector could be just like any other vector. I somehow confused the cross product with the curl of a vector. Sorry about my confusion everyone. Once again, I am sorry for making anyone upset and frustrated. Just some confusion HallsofIvy.
