🔹 How to Use the Integral Calculator (with Steps)

🧾 Basic Instructions:

1. Input the Function
   Enter the expression you want to integrate. Example: ∫(3x^2 - 2x + 1) dx
2. Specify the Variable of Integration
   Most calculators default to x, but you can change it to y, t, etc.
3. Choose Integration Type
   • Indefinite Integral (no limits)
   • Definite Integral (with upper and lower bounds)
4. Click “Calculate”
   The calculator will show:
   • The final result
   • Step-by-step workings (e.g., applying rules, substitution, simplification)

🔹 Example Calculation

Input: ∫(2×3−4x+5) dx\int (2x^3 – 4x + 5)\,dx∫(2×3−4x+5)dx

Steps:

1. Apply the power rule: ∫xn dx=xn+1n+1\int x^n\,dx = \frac{x^{n+1}}{n+1}∫xndx=n+1xn+1​
2. Integrate term-by-term:
   • ∫2×3 dx=2×44=x42\int 2x^3\,dx = \frac{2x^4}{4} = \frac{x^4}{2}∫2x3dx=42×4​=2×4​
   • ∫−4x dx=−2×2\int -4x\,dx = -2x^2∫−4xdx=−2×2
   • ∫5 dx=5x\int 5\,dx = 5x∫5dx=5x

Result: x42−2×2+5x+C\frac{x^4}{2} – 2x^2 + 5x + C2x4​−2×2+5x+C
