    In physics and mathematics, a pseudovector (or axial vector) is a quantity that transforms like a vector under a proper rotation, but gains an additional sign flip under an improper rotation such as a reflection. Geometrically it is the opposite, of equal magnitude but in the opposite direction, of its mirror image. This is as opposed to a true or polar vector (more formally, a contravariant vector), which on reflection matches its mirror image.In three dimensions the pseudovector p is associated with the cross product of two polar vectors a and b: P=AxB

    basically, the resulting vector, after TWO vectors perform a cross product, is a pseudovector. If you can read English well, please refer to:
