But the three OTHER permutations of 1, 2, and 3 are 321, 213, 132, which are the reverse of the above, and that confirms what we should already know -- that reversing the order of a cross product gives us the OPPOSITE result: 213: j X i = -k. 321: k X j = -i. 132: i X k = -j.When two nonzero vectors are placed in standard position, whether in two dimensions or three dimensions, they form an angle between them (Figure 2.44). The dot product provides a way to find the measure of this angle. This property is a result of the fact that we can express the dot product in terms of the cosine of the angle formed by two vectors. Therefore, the dot product of two parallel vectors can be determined by just taking the product of the magnitudes. Cross product of parallel vectors The Cross product of the vector is always a zero vector when the vectors are parallel. Let us assume two vectors, v and w, which are parallel. Then the angle between them is 0°.Since the dot product is 0, we know the two vectors are orthogonal.
