Antiderivative Calculator

```html ```

In calculus, an antiderivative is the reverse process of differentiation.
If differentiation finds the rate of change of a function, the antiderivative finds the original function whose derivative gives that result.

It’s also called an indefinite integral because it doesn’t include limits of integration.
In simple terms:

If F′(x)=f(x)F'(x) = f(x)F′(x)=f(x), then F(x)F(x)F(x) is an antiderivative of f(x)f(x)f(x).

For example: ∫2x dx=x2+C\int 2x \, dx = x^2 + C∫2xdx=x2+C

Here, x2+Cx^2 + Cx2+C is the antiderivative of 2x2x2x.

🧠 Antiderivative Formula

The general formula for finding the antiderivative of a function f(x)f(x)f(x) is: F(x)=∫f(x) dxF(x) = \int f(x) \, dxF(x)=∫f(x)dx

Where F(x)F(x)F(x) is the antiderivative, and CCC is the constant of integration (since many functions can have the same derivative).

✨ Example Calculation

Let’s find the antiderivative of f(x)=6x2f(x) = 6x^2f(x)=6×2.

Step 1: Write the expression ∫6×2 dx\int 6x^2 \, dx∫6x2dx

Step 2: Apply the power rule ∫xn dx=xn+1n+1+C\int x^n \, dx = \frac{x^{n+1}}{n+1} + C∫xndx=n+1xn+1​+C

Step 3: 6×x33+C=2×3+C6 \times \frac{x^{3}}{3} + C = 2x^3 + C6×3×3​+C=2×3+C

✅ Result: F(x)=2×3+CF(x) = 2x^3 + CF(x)=2×3+C

The Antiderivative Calculator gives you this instantly — without any manual computation.
