What is Integralcalculator.info?
Integralcalculator.info is a free educational website for calculus practice. It provides online calculators, examples, and concept explanations for integrals, derivatives, limits, series, transforms, multivariable calculus, vector calculus, and differential equations.
Is the integral calculator free?
Yes. The calculator pages are free to use. We may apply fair-use limits so the service remains available and stable for real visitors.
Which calculators are available?
The site includes calculators for indefinite integrals, definite integrals, double integrals, triple integrals, improper integrals, derivatives, partial derivatives, second derivatives, implicit derivatives, limits, one-sided limits, series, Taylor series, Laplace transforms, inverse Laplace transforms, Fourier series, gradients, divergence, curl, and differential equations.
Why do examples change by calculator?
Each calculator has its own examples because a derivative example should not look like a triple integral example. Topic-specific examples help students understand the calculator purpose before entering their own problem.
Do the calculators show steps?
Yes. The solution area is designed to show a final answer and short step-by-step explanation blocks. The goal is to help students learn the method, not only copy the result.
Can the calculator make mistakes?
Yes. Automated math tools can misunderstand notation, variables, bounds, or the intended operation. Always review the interpretation and verify important answers with a teacher, textbook, or another reliable source.
Why does the site ask for a variable?
The variable tells the calculator which symbol to use when solving. For example, an integral with respect to x can have a different meaning from an integral with respect to t.
Why do some calculators not show From and To boxes?
Only calculators that need bounds or centers show those extra fields. An indefinite integral usually needs a variable but not a numerical range, while a definite integral needs lower and upper limits.
Can I link to a calculator from my website?
Yes. You may link to any public calculator page on Integralcalculator.info. Please link to the specific calculator URL when possible, such as /calculus/integral-calculator.
Do you have a calculator API?
No public API is currently available. The calculators are intended for direct use on the website.
How do I report a wrong answer or broken page?
Use the Contact Us page. Please include the calculator URL, your exact input, selected variable, bounds if any, and a short note about what looked wrong.
Do you store user accounts?
No. The website does not offer user accounts or personal dashboards. Some technical request data may be logged for rate limiting, security, diagnostics, and contact form handling.
Why is there a daily request limit?
Request limits help prevent automated abuse and keep the service responsive. Limits may be based on IP address and related technical signals.
Does the site use cookies?
Yes, some cookies or similar technologies may be used for sessions, security checks, ads, and analytics or measurement where enabled. See the Privacy Policy and Cookie Policy for details.
How can I advertise?
