    Help with a linear algebra rule

    Hello,

    Can anyone help to identify the name of this linear algebra rule:

    |A, B, C| = -(A cross C) dot B = -(C cross B) dot A
    If it doesn't have a name, can anyone briefly tell me what it does or how it works or where should I look for an explanation, thank you very much.

    It's called a triple scalar product.

    And it is NOT from "linear algebra". The cross product is defined only in R^3, not in a general finite dimensional vector space.
