Cross Product is a method used to multiply any two vectors. Here, we are giving the simple steps to calculate the cross product of vectors. Follow these steps and solve your vectors effortlessly.

- Take any two vectors of same order.
- Represent the given two vectors as matrix. Where first row is a unit vector, second row is our first vector and the third row is the second vector. .
- To check the vector cross product, we need to perform the determinant of matrix.
- Expand the matrix and find the det matrix value.
- The formed coefficients of the unit vector will be the cross product of two vectors.

The formula to compute the cross product of two different vectors is given below:

a x b = │a││b│ sin(θ) nwhere,

a, b are the two different vectors

θ is the angle between those vectors

n is the unit matrix.

**Example**

**Question: Calculate the cross product between a=(3,−3,1) and b=(4,9,2)?**

**Solution:**

Given vectors are

a=(3,−3,1) and b=(4,9,2)

The matrix will be

i j k

a x b = 3 -3 1

4 9 2

│a x b │ = i(-3*2 - 1*9) -j(3*2-1*4)+ k(3*9 + 3*4)

= i(-6-9) -j(6-4)+ k(27+12)

= -15i-2j+39k

a x b = (-15, -2, 39)

(3,−3,1) x (4,9,2) = (-15, -2, 39)

**1. What do you mean by Cross Product?**

Cross product is a binary operation of two vectors in a three dimensional space. It is also called as vector product. The formula to find the cross product of vectors is a x b = │a││b│ sin(θ) n

Where a,b are the two vectors

θ is the angle between two vectors

││ is the magnitude

n is the unit vector.

**2. What happens when you cross product of identical vector?**

When you calculate the cross product of identical vectors, it produces a degenerate parallelogram with no area. The cross product will become zero.

**3. Calculate the area of the parallelogram spanned by the vectors a=(3,−3,1) and c=(−12,12,−4).**

Vectors are

a=(3,−3,1) and c=(−12,12,−4)

│a x c│ = i j k

3 -3 1

-12 12 -4

=i(-3x-4 -12x1) + j(-12x1 - 3x-4) +k(3x12 - (-3)x(-12)

=i(12-12)+ j(-12+12)+ k(36-36)

=(0,0,0)

The magnitude of zero vector is zero, so the area of the parallelogram is zero.

**4. What is cross product used for?**

The cross product is used to find a vector which is perpendicular to the plane spanned by two different vectors. It has many applications in physics when dealing with the rotating bodies.

**5. Find the angle between two vector a and b, where a =(-4, 3, 0) and b =(2, 0, 0)?**

The formula to get the angle between two vectors is

sin(θ) = a x b / │a││b│

θ = sin^{-1}(a x b / │a││b│)

First calculate a x b

a x b = i(0) -j(0)+k(-6)

=-6k

│a│ = √-4^{2}+3^{2}+0^{2}

=√16+9 = √25 = 5

│b│ = √2^{2}+0^{2}+0^{2}

=2

We know that θ = sin^{-1}(a x b / │a││b│)

θ = sin^{-1}(-6 / 5x2)

=sin^{-1} (3/5) = 36.87°

Hence, the angle is 36.87°.
