    Who? I know: you can do this!

    Do you know how to substitute values into a function? Basically, you have a function
    $$f(x_1,y_1,x_2,y_2)=x_1y_2-x_2y_1.$$
    How do you expand
    $$f(x_2,y_2,x_1,y_1)$$
    according to the definition above?

    Re: Vectors

    It was, simply, an exercise in reading and applying a definition. Nothing unusual about that.
