A derivative helps us to know the changing relationship between two variables. Consider the independent variable ‘x’ and the dependent variable ‘y’. The change in the value of the dependent variable with respect to the change in the value of the independent variable expression can be found using the derivative formula. Mathematically, the derivative formula is helpful to find the slope of a line, to find the slope of a curve, and to find the change in one measurement with respect to another measurement. In this section, we will learn more about the derivative formula and solve a few examples.
What is Derivative Formula?
The derivative formula is one of the basic concepts used in calculus and the process of finding a derivative is known as differentiation. The derivative formula is defined for a variable ‘x’ having an exponent ‘n’. The exponent ‘n’ can be an integer or a rational fraction. Hence, the formula to calculate the derivative is:

There are some basic derivative formulas i.e. a set of derivative formulas that are used at different levels and aspects. The below image has the rules.
Derivation of Derivative Formula
Let f(x) is a function whose domain contains an open interval about some point x0x0. Then the function f(x) is said to be differentiable at point (x)0(x)0, and the derivative of f(x) at (x)0(x)0 is represented using formula as:
f'(x)= limΔx→0 Δy/Δx
⇒ f'(x)= limΔx→0 [f((x)0(x)0+Δx)−f((x)0(x)0)]/Δx
Derivative of the function y = f(x) can be denoted as f′(x) or y′(x).
Also, Leibniz’s notation is popular to write the derivative of the function y = f(x) as df(x)/dx i.e. dy/dx
