About the Integral Calculator
standard opportunityThe Integral Calculator is a free online calculus tool designed to calculate definite and indefinite integrals with step-by-step antiderivative steps. If you are calculating the rate of change instead of accumulation, you can swap to our Derivative Calculator, or use the Decimal Calculator to evaluate numeric outputs.
This tool integrates polynomials, trigonometric functions, and exponential expressions. For definite integration, it features a live SVG visualizer showing the shaded area under the curve between your lower and upper limit parameters.
Formulas & Mathematical Theory
Power Rule of Integration
To integrate a variable raised to a power, increase the exponent by one and divide the term by the new exponent, adding a constant of integration C.
Definite Integral Substitution (FTC)
Evaluate a definite integral by subtracting the antiderivative evaluated at the lower limit from the antiderivative evaluated at the upper limit.
What This Tool Does
This calculator focuses on interactive calculation, which means the page is structured around a clear input area, a focused results panel, and a short path from first interaction to useful output.
Users searching for integral calculator usually want a fast answer, but they also need enough surrounding context to trust what they are seeing. That is why this page pairs the live tool with supporting sections, usage guidance, FAQs, and related links.
