Calculus is one of the most important branches of mathematics, and at its heart lies the concept of the derivative. Whether you’re a high school student just starting calculus or a college learner brushing up on advanced topics, mastering derivatives is essential.
But let’s face it—working through long derivative problems by hand can sometimes be overwhelming. That’s where our online Derivative Calculator comes in handy. It doesn’t just give you the answer—it helps you practice, verify, and learn step by step.
📌 What Is a Derivative?
In simple terms, a derivative measures how a function changes.
- For a straight line, the derivative is the slope (rise over run).
- For curves, the derivative tells you the slope of the tangent line at any given point.
Mathematically, if f(x)f(x)f(x) is a function, then its derivative f′(x)f'(x)f′(x) is defined as:
f′(x)=h→0limhf(x+h)−f(x)This formula may look intimidating at first, but with practice—and the right tools—it becomes second nature.

✅ Example Walkthrough
Let’s solve a problem together:
Problem: Differentiate f(x)=3×3+5×2−7f(x) = 3x^3 + 5x^2 – 7f(x)=3×3+5×2−7.
Steps:
- Power rule: d/dx[xn]=n⋅xn−1d/dx[x^n] = n \cdot x^{n-1}d/dx[xn]=n⋅xn−1.
- Apply rule term by term:
- d/dx[3×3]=9x2d/dx[3x^3] = 9x^2d/dx[3×3]=9×2
- d/dx[5×2]=10xd/dx[5x^2] = 10xd/dx[5×2]=10x
- d/dx[−7]=0d/dx[-7] = 0d/dx[−7]=0
Final Answer: f′(x)=9×2+10xf'(x) = 9x^2 + 10xf′(x)=9×2+10x
With our calculator, you can input this function and see the same step-by-step process automatically.
