# Basic Differentiation Rules [Aturan Dasar Turunan]

The derivative of a function $f$ is another function $f'$ [read "$f$ prime"] whose value at any number $x$ is $f'(x)=\lim\limits_{h \to 0} \dfrac{f(x+h)-f(x)}{h}$.

If this limit does exist, we say that $f$ is differentiable at $x$. Finding a derivative is called differentiation; the part of calculus associated with the derivative is called differential calculus.

With Leibniz notation, introduced in the last section, we now have three notations for the derivative. If $y=f(x)$, we can denote the derivative of $f$ by $f'(x)$ or $D_{x}f(x)$ or $\dfrac{dy}{dx}$
