Derivative of a variable
Formula
$\dfrac{d}{dx}{\, (x)} \,=\, 1$
The derivative of a variable with respect to same variable is equal to one.
Introduction
$x$ is a variable and the differentiation of a variable $x$ with respect to $x$ is written in the following mathematical form.
$\dfrac{d}{dx}{\, (x)}$
In differential calculus, the derivative of variable $x$ is written as $\dfrac{d(x)}{dx}$ alternatively and also simply written as $x’$.
Therefore, $\dfrac{d}{dx}{\, (x)} \,=\, 1$
Other forms
The differentiation rule for a variable can be written in terms of any variable but its derivative is always one.
$(1) \,\,\,$ $\dfrac{d}{dm}{\, (m)} \,=\, 1$
$(2) \,\,\,$ $\dfrac{d}{dq}{\, (q)} \,=\, 1$
$(3) \,\,\,$ $\dfrac{d}{dy}{\, (y)} \,=\, 1$
