2. What is a Derivative?
In mathematics, a derivative measures how a function changes as its input changes. It’s a core concept in calculus, representing the rate of change or slope of a function at a given point.
For example:
-
The derivative of x² is 2x
-
The derivative of sin(x) is cos(x)
Derivatives are used in physics (motion), economics (growth), engineering (rates), and data science (optimization). Learning how to compute them is essential for students and professionals alike.
3. Why Use an Online Free Derivative Calculator?

Instantly see the derivative result
This is a FREE and interactive way to explore calculus without installations or signups.
5. Manual Derivative Example
Let’s differentiate this by hand:
f(x) = x³ + 5x² – sin(x)
Using standard rules:
-
d/dx(x³) = 3x²
-
d/dx(5x²) = 10x
-
d/dx(-sin(x)) = -cos(x)
So,
f’(x) = 3x² + 10x – cos(x)
You can verify this instantly using our FREE online Derivative Calculator.
6. Supported Functions & Rules
Our derivative calculator supports:
-
🧠 Polynomial functions (e.g., x^5, 3x² + 7x)
-
📉 Trigonometric: sin(x), cos(x), tan(x)
