# Differential Calculus

The derivative of a function at a point is the rate of change of the slope of the tangent line at that point. We will discuss its definition along with its various properties and many solved examples on this page.

## Definition of Differentiable Function

Let f(x) be a function of the real variable x and let D denote the domain of f(x). The function f(x) is said to be differentiable on D if the following limit exists:

limhâ†’0 $\dfrac{f(x+h)-f(x)}{h}$

for all values of x in D. It is denoted by $f'(x)$ or $\dfrac{d}{dx}(f(x))$.
