# Vector Product of Vectors

In this lesson on vectors, we’ll be talking about vector product or cross product of vectors.

## How to denote vector or cross product in Math

In Math, we denote vector product with a ✕, hence vector products are also called cross product.

## The result of vector product

When we cross 2 vectors, we are finding a vector that is perpendicular to both of these vectors. Hence, the result of a cross product is a vector.

If we have vectors given in x, y or x, y, z coordinate form, we can find unit vector using the following formula. Note that this formula is provided in the formula booklet (for students taking the H2 A Level Math exam).

The video below shows how to find vector product (or cross product) of vectors in detail:

## Useful results of vector product (cross product)

1. When we take the cross product of two vectors, the result is a vector perpendicular to both of these vectors.
2. |a x b| gives the area of a parallelogram with sides a and b.
3. If 2 vectors are parallel, cross product will give a value of 0.
4. a x a = 0
