Integral Calculator
Symbolic integral calculator for indefinite and definite polynomial integrals. See antiderivative steps, parse diagnostics, and export integral reports with bound evaluation.
How to use this tool
- Write your integrand as a polynomial in x using powers with ^, or choose an example expression.
- Review the symbolic antiderivative F(x) + C and the power-rule step breakdown.
- Optionally set bounds a and b, then copy or download the integral report.
Ideal online integral calculator for early calculus
- Practice turning derivatives back into antiderivatives using a friendly integral calculator.
- See exactly how each exponent increases by one in the power rule ∫ a x^n dx = a x^(n+1)/(n+1).
- Use definite integrals to compute the exact area under simple polynomial curves.
What this integral calculator supports
- Polynomials in x with real coefficients and whole-number powers using the power rule.
- Indefinite integrals with + C as well as optional definite integrals between two bounds.
- Readable step-by-step integral explanations plus parse diagnostics for unsupported terms.
FAQ
- Can this step-by-step integral calculator integrate 1/x or trig functions?
- This mode focuses on polynomial power-rule integrals. Terms like 1/x, trig functions, exponentials, or roots require additional rules and are flagged in diagnostics.
- Does order of terms matter in the integrand?
- No. The calculator will parse your sum of terms and present the antiderivative in a cleaned, highest-power-first form.
- Is numeric integration or approximation available?
- For polynomials, the exact definite integral is computed via the antiderivative, which is more accurate and reliable than approximate numerical methods for these functions.
