What is Cross Product?
A vector that is perpendicular or orthogonal to both vectors is the cross-product of any two vectors. The cross product is a vector product as direction and magnitude both are present in it. The length of the vector is equal to the parallelogram, the side lengths of which are equal to the size of both vectors. The angle of the resulting vector also corresponds to the angle of the two vectors.
However, according to its formula a × b = |a| |b| sin(θ) n
the cross product of two vectors can also be defined as
A technique for two vectors to multiply, where || denotes magnitude or length of θ angle among vectors whereas the n represents the vector unit right-angled to both the vectors a b.
By calculating the product of the magnitudes of the vector times the sine (<180 degrees) between the vectors, the vector product’s magnitude of two vector types is determined.
What is the Significance of Cross Product?
The vector product of two vectors, the cross product has a significant role in many geometric and physical operations and derivations. For instance, geometrically, if you had two vectors in your plane, the vector product or cross product is useful as a means to make a vector perpendicular to a plane.
Furthermore, certain other geometric applications where the cross product is crucial to use include area of triangle/parallelogram, the angle between two vectors using vector product and unit vector perpendicular to two vectors, collinearity of two vectors.
Torque, the fundamental concept of work and force in physics also utilizes the notion of the cross product. Besides the torque calculation in physics, the magnetic force calculation for a moving charge obeys the same rules and concepts of vector product.
As we know that the cross product makes it possible to construct a vector perpendicular to the two vectors, to measure the parallelogram area and the volume of a parallelepiped. And thus it becomes apparent that the cross product also lets us define a physical amount termed torque, apart from the geometric uses.
Let us consider the example for torque, according to the Second Law of Newton on an object when the force is applied, it is equal to the rate of change in the linear momentum of the object. The rate of change in an object’s angular momentum is the torque given to an item. This means that the bolt rotates with a torque according to the cross-product rules.

What is Integration?
The word “integral” derives from the word “whole” in Latin. The total change in amount constitutes an integral element. If you want to know the total change, and you know how it changes at any time, simply integrate the rate of change. However, integration is the opposite distinguishing process.
The integration indicates that discrete data are summarized. The integral function is calculated to identify the area, displacement, and volume functions that arise because little data gathering cannot be measured single.
What is Integrand?
The integrand is an integral equation or integration formula, it is denoted as the function f(x). In the integration, the area under the curve might write in a mathematical form in the form of function f(x).
That function f(x) is the integrand which we will write under the sign of integral.
For Example:
∫cos(x)dx
here, cos(x) is an integrand of that integral.

What is the Significance of Integration?
In its own way, integration is beautiful and essential in life. There is truly endless real-world integration uses and they surround us everywhere. We need it when, for example, we talk about quantum mechanics. The cellphone we are having in this era is a quantum mechanics marvel. In reality, the integration rendered your mobile phone transitory.
Integration is just a more advanced additional tool. You add little quantities, yet many, and this will do to make sense according to the situation. Moreover, you can determine the region underneath the curves with accuracy.
Thus the most frequent way of utilizing the integration notion is to compute the area under a curve. The integration will use to measure things if we recall from a broader standpoint.
let it be the length, area, and volume, in a specific sense, it also measures the behavior of functions.
In fact, physics needs integration because as time or space continues, it approaches infinity. So integration will employ if addition is not enough because of its limited character. Also, the integration will use everywhere.
