Cross product, determinant

  1. Sep 29, 2014 #1
    Is this just a coincidence that cross product can be found from determinant of 3*3 matrix?


    what is the differences between wedge product and cross product?


    Thanks.

    No.
    It is another way of writing the definition.

    Basically the wedge product is a generalization of the cross-product to any vector space.

    For one, the wedge product is defined on forms, and the cross-product is defined on vectors.
