Cross Product. The cross product is a binary operation on two vectors in three-dimensional space. It again results in a vector which is perpendicular to both vectors. The cross product of two vectors is calculated by the right-hand rule. The right-hand rule is the resultant of any two vectors perpendicular to the other two vectors.

It results in a vector that is perpendicular to both vectors. The Vector product of two vectors, a and b, is denoted by a × b. Its resultant vector is perpendicular to a and b. Vector products are also called cross products. Cross product of two vectors will give the resultant a vector and calculated using the Right-hand Rule.

Cross product is a binary operation on two vectors, from which we get another vector perpendicular to both and lying on a plane normal to both of them. The direction of the cross-product is given by the Right Hand Thumb Rule. If we curl the fingers of the right hand in the order of the vectors, then the thumb points to the cross-product.b × c = (b1i +b2j +b3k) × (c1i + c2j +c3k) gives.

Using this equation, we can find the cosine of the angle between two nonzero vectors.

This multiplication rule can be interpreted as taking the length of one of the vectors multiplied by a factor equal to the length of the other. The inner product in the case of parallel vectors that point in the same direction is just the multiplication of the lengths of the vectors, i.e., a ⋅b = |a ||b |. It follows from the definition that ... The dot product of unit vectors \(\hat i\), \(\hat j\), \(\hat k\) follows similar rules as the dot product of vectors. The angle between the same vectors is equal to 0º, and hence their dot product is equal to 1.
