If $x = [x_0,x_1,x_2]^T$ and $z = [z_0,z_1,z_2]^T$ are column vectors, then evaluate:

$x^T \cdot z$ (dot product)

$x \cdot z^T$ (matrix product)

$x \times z$ (cross product)

dot product= Xo.Zo + X1.Z1 +X2.Z2

matrix product= Xo.Zo + Xo.Z1 + Xo.Z2

cross product= Cx= X1.Z2 - X2.Z1

                        Cy=X2.Zo - Xo.Z2

                       Cz=Xo.Z1 - X2.Zo

dot product: x0. z0 + x1. z1 + x2. z2

matrix product: x0.z0 + x0.z1 +x0.z2

cross product: cx = x1.z2 - x2.z1 ; cy = x2.z0 - x0.z2; cz = x0.z1 - x1.z0
