To find the cross product of two vectors:

If a = [a1, a2, a3] and b = [b1, b2, b3], then

a x b = [a2b3 - a3b2, a3b1 - a1b3, a1b2 - a2b1] or(a2b3 - a3b2)i + (a3b1 - a1b3)j + (a1b2 - a2b1)k

How do you multiply vectors in 3D?

To multiply two vectors in 3D, you can use the dot product or the cross product. The dot product results in a scalar quantity, while the cross product produces a new vector that is perpendicular to the original two vectors.


Why the cross product of two vectors in plane is directed perpendicular to the plane?

because that is the def. of a cross-product!


What does the cross product of two vectors represent in mathematics?

The cross product of two vectors in mathematics represents a new vector that is perpendicular to both of the original vectors. It is used to calculate the area of a parallelogram formed by the two original vectors and to determine the direction of a resulting force in physics.


What is the product of two vector quantities?

It depends on the type of product used. A dot or scalar product of two vectors will result in a scalar. A cross or vector product of two vectors will result in a vector.


Cross product is?

Cross product is a mathematics term when there is a binary operation on two vectors in three-dimensional space.


Why is magnetic field vector a pseudo vector?

It is the cross product of two vectors. The cross product of two vectors is always a pseudo-vector. This is related to the fact that A x B is not the same as B x A: in the case of the cross product, A x B = - (B x A).


What is a cross product?

The cross product is a mathematical operation that takes two vectors in three-dimensional space and produces a third vector that is perpendicular to both of the original vectors. It is denoted as ( \mathbf{A} \times \mathbf{B} ) and is calculated using the determinant of a matrix formed by the unit vectors and the components of the two vectors. The magnitude of the cross product represents the area of the parallelogram formed by the two vectors, and its direction is determined by the right-hand rule. The cross product is only defined in three dimensions and is widely used in physics and engineering to describe rotational effects and torque.


Why the product of two vectors is sometime scalar and sometime vector?

Because there are two different ways of computing the product of two vectors, one of which yields a scalar quantity while the other yields a vector quantity.This isn't a "sometimes" thing: the dot product of two vectors is always scalar, while the cross product of two vectors is always a vector.


What is the algebraic definition of a cross product?

Cross product also known as vector product can best be described as a binary operation on two vectors in a three-dimensional space. The created vector is perpendicular to both of the multiplied vectors.


What does the cross product represent in vector algebra?

The cross product in vector algebra represents a new vector that is perpendicular to the two original vectors being multiplied. It is used to find the direction of a vector resulting from the multiplication of two vectors.


Is the cross product vector or scalar?

The cross product is a vector. It results in a new vector that is perpendicular to the two original vectors being multiplied.


What is cross in science?

One type of cross is the cross or vector product of a pair of 3D vectors. If there are two unit vectors that are not parallel, their vector product is a vector that is normal to the plane containing the two vectors, so it's a good way to find that plane. In biological science, cross signifies the mating of two genotypes to produce its progeny. It may be among homozygous or heterozygous parents.
