What is a Derivative?
In mathematics, the derivative represents the rate at which one quantity changes compared to another.
For example:
- Speed is the derivative of distance with respect to time
- Acceleration is the derivative of velocity
- Growth rate is the derivative of a population function
The standard derivative formula is:
f'(x) = lim h→0 [f(x+h) − f(x)] / h
This formula measures the slope of the tangent line to a curve at a specific point.
Our calculator simplifies this entire process and gives instant results.
How the Derivative Calculator Works
The Derivative Calculator uses differentiation rules to calculate the derivative of the entered function.
These rules include:
Power Rule
For:
f(x) = x^n
Derivative:
f'(x) = n × x^(n−1)
Example:
x^3 → 3x^2
Product Rule
For:
f(x) = u × v
Derivative:
f'(x) = u’v + uv’
Quotient Rule
For:
f(x) = u / v
Derivative:
f'(x) = (u’v − uv’) / v²
Chain Rule
For composite functions:
f(x) = g(h(x))
Derivative:
f'(x) = g'(h(x)) × h'(x)
Trigonometric Derivatives
Examples:
- d/dx (sin x) = cos x
- d/dx (cos x) = −sin x
- d/dx (tan x) = sec²x
Logarithmic and Exponential Derivatives
Examples:
- d/dx (ln x) = 1/x
- d/dx (e^x) = e^x

Practical Examples
Example 1: First Derivative
Function:
f(x) = x^4 + 3x^2
Derivative:
f'(x) = 4x^3 + 6x
This shows how the function changes at every value of x.
Example 2: Second Derivative
Function:
f(x) = x^3
First derivative:
f'(x) = 3x^2
Second derivative:
f”(x) = 6x
This helps analyze acceleration and curve behavior.
Example 3: Trigonometric Function
Function:
f(x) = sin(x)
Derivative:
f'(x) = cos(x)
This is commonly used in physics and engineering.
Example 4: Exponential Function
Function:
f(x) = e^x
Derivative:
f'(x) = e^x
This is widely used in growth and decay models.
