Integral Calculator - Wolfram|Alpha
Wolfram|Alpha's Integral Calculator takes indefinite and definite integrals, including double, triple, and improper forms, from natural language or Math Input. You get antiderivatives, numeric results, plots, alternate forms, and series expansions in one response. The page lives inside Wolfram|Alpha's computational knowledge engine rather than acting as a stripped-down homework widget.
Most free integral sites stop at a final answer. Wolfram|Alpha routes work through Mathematica's Integrate engine, which uses symbolic algorithms and generalized hypergeometric methods instead of mimicking pencil-and-paper steps. That trade-off favors breadth and speed over showing every intermediate move unless you upgrade to Pro for step-by-step calculus breakdowns.
Students checking homework, engineers validating symbolic math, and teachers building practice sets all use it. The page links to Wolfram Problem Generator for unlimited calculus drills and to related calculators for derivatives, limits, and multivariate integrals when a problem spans more than one operation.

Interface pushes Pro upgrades for learning tools beyond raw answers
Pricing page shows region-specific amounts that may differ from US rates
Is the Wolfram|Alpha Integral Calculator free?
Yes. The Integral Calculator on Wolfram|Alpha works without payment for core symbolic and numeric integral results. Wolfram|Alpha Pro adds step-by-step solutions, extended computation time, and practice tools starting at $5 per month when billed annually.
What types of integrals can Wolfram|Alpha solve?
The Wolfram|Alpha Integral Calculator handles antiderivatives, definite integrals over intervals, double and triple integrals, and improper integrals. Results can include plots, alternate forms, and series expansions when they help explain the answer.
Does Wolfram|Alpha show step-by-step integral work?
Wolfram|Alpha shows final integral results for free, but detailed step-by-step calculus breakdowns require Wolfram|Alpha Pro. Pro subscribers get methods such as substitution, integration by parts, and trigonometric substitution explained in sequence.
How do I enter an integral on Wolfram|Alpha?
On the Integral Calculator page, type plain English such as integrate x/(x-1) or use Math Input for structured notation. Wolfram|Alpha parses either format and runs the query through its computational knowledge engine.
Can Wolfram|Alpha integrate multivariable expressions?
Yes. Wolfram|Alpha accepts multivariate integrals with explicit bounds, for example integrate x^2 sin y dx dy with x from 0 to 1 and y from 0 to pi. The calculator page links to dedicated double and triple integral tools for related problems.
What is Wolfram Problem Generator on the integral page?
Wolfram Problem Generator is a separate Wolfram|Alpha learning tool linked from the Integral Calculator. It creates unlimited calculus practice problems with hints and step-by-step solutions for Pro users who want repeated drills beyond a single query.
