Question

Why is it called differentiation ?

Answer 1

Differentiation is the process of derivation for the given functions or terms.
Differentiation can be defined as the derivative of the independent variable value and can be used to calculate features in an independence variance per unit modification.

Complete step-by-step solution:
In other words, the definition of the derivative is actually the rate of change of a particular function.
So, the differentiation formula is $\dfrac{{dy}}{{dx}}$ . It shows that the difference in y is divided by the difference in x and also d is not the variable.
There are several processes of differentiation: Sum and difference rule, Product rule, chain rule, and Quotient Rule.
Differentiation for the trigonometric is defined as the interaction of the angles and triangle faces, we have six major ratios sine, cosine, tangent, cotangent, secant, and cosecant.
Based on these ratios we must have interrelated trigonometric formulas like $\dfrac{{d(\sin x)}}{{dx}} = \cos x$
Hence, due to the small difference in the process of derivation, we called it the definition function.
Additional information:
Integration is the process of inverse differentiation.
Process of finding the functions whose derivative is given named anti-differentiation or integration.
Integration is the process of adding the slices to find their whole.
It can be used to find the area, volume, and central points.
The integration is $\int\limits_a^b {f(x)dx}$ the value of the anti-differentiation at the upper limit b and the lower limit a with the same anti-differentiation.

Note: Differentiation and integration are inverse processes like a derivative of $\dfrac{{d({x^2})}}{{dx}} = 2x$ and the integration is $\int {2xdx = \dfrac{{2{x^2}}}{2}} \Rightarrow {x^2}$
In differentiation, the derivative of $x$ raised to the power is denoted by $\dfrac{d}{{dx}}\left( {{x^n}} \right) = n{x^{n - 1}}$ .
The inverse of the function is defined as ${x^{ - 1}} = \dfrac{1}{x}$
