Q:
# What is the cross product of a vector?

There is one requirement that must be satisfied in order to find a cross product: Both of the vectors need to be three-dimensional vectors. This is because the result of a cross product is another vector, also known as a vector product, and not a number as is the case with the result of the dot product.
