## Differentiation Calculator

Differentiation calculator is an online calculus tool that finds the derivative of a given function. This derivative calculator can perform explicit differentiation with just one click.

Our differential calculator shows the solution with steps in a couple of seconds.

## Derivative – Definition

Let f(x) be a function whose domain contains an open interval at some point x0. The function f(x) is said to be differentiable at x0, and the derivative of f(x) at x0 is given by:

In other words, derivative measures the sensitivity to change of the function value with respect to a change in its argument. The reverse function of derivative is known as antiderivative.

## How to calculate derivative?

To differentiate a function, you can use d/dx calculator above. Let’s calculate the derivative of 1/x to grasp the basic idea of derivation.

As 1/x = x-1

We will use product rule (refer to below rules).

d/dx (x-1) = -1(x-2) = - 1/x2

Example:

Find the derivative of (x+7)2.

Solution:

Step 1: Apply derivation symbol.

Step 2: Apply power rule.

Some functions need second derivative to complete the process of differentiation. You can use our second derivative calculator in this case.

## Derivative rules – Formulas

 Rules Name Rules Constant Rule d/dx [k] = 0 Power Rule d/dx [xa] = a * xa-1 Sum Rule [f(x) + g(x)]' = f'(x) + g'(x) Difference Rule [f(x) - g(x)]' = f'(x) - g'(x) Product Rule [f(x) * g(x)]' = f'(x) g(x) + g'(x) f(x) Quotient Rule [f(x) / g(x)]' = [f'(x) g(x) - g'(x) f(x)]/[g(x)]2 Chain Rule If f(x) = hg(x) f'(x) = h'(g(x)) * g'(x) Trigonometric Derivatives d/dx cos(x) = -sin(x) d/dx sin(x) = cos(x) d/dx tan(x) = sec2(x) = 1 + tan2(x) Derivative of e^x (Exponential) d/dx e^x = e^x Logarithm Derivatives d/dx a^x = ax ln(a), a>0 d/dx ln(x) = 1/x, x>0 d/dx logx(x) = 1/(x ln(a)), x>0
