    About the Integral Calculator

    Welcome to the ultimate Integral Calculator, a free online tool designed to help students, engineers, and mathematicians solve complex integration problems instantly. Whether you need to find the area under a curve (Definite Integral) or find the antiderivative of a function (Indefinite Integral), this tool provides accurate results.

    How to Use This Tool?

    • Enter the Function: Type your math equation in the f(x) box. Use standard notation like x^2 for powers, sin(x) for trigonometry, and log(x) for logarithms.
    • Select Type: Choose "Indefinite" to get the symbolic formula or "Definite" to calculate numerical values within limits.
    • Set Limits: If calculating a definite integral, enter the lower (a) and upper (b) limits.
    • Export Data: You can save your results as a PDF report or a CSV file for your records.

    Key Features

    • Symbolic Integration: Solves algebraic formulas (e.g., ∫ x dx = x²/2 + C).
    • Numerical Integration: Uses advanced algorithms to calculate precise areas.
    • Mobile Responsive: Works perfectly on phones, tablets, and desktops.
    • Privacy Focused: All calculations happen in your browser; no data is sent to servers.
