    Part I:

    <(u x v), u> is greater than 0 for all vectors u and v in R^3.

    Part II:

    The equation of the plane through the origin determined by two vectors u and v in R^3 is <(u x v), x> = 0.

    Are these statements true or false and please explain why.

    I. The statement is false. The cross-product u x v is perpendicular to both u and v, and so the dot product of (u x v) and u is zero for all u and v from R^3.

    II. This statement is true. The equation of a plane can be derived as follows: ...
