Disclaimer

For education, not certification

GraphCalc is built to help people learn and check mathematics. It is not a certified instrument and is not a substitute for professional judgement. It is best used to explore ideas, visualise functions, and confirm work you have reasoned through yourself.

Results are provided as is

Every calculator on this site is offered without warranty of any kind, express or implied. We aim for correctness and test the tools against known mathematics, but we cannot guarantee that every result is accurate in every case. Numerical methods approximate, floating-point arithmetic rounds, and edge cases exist. A graph or value shown here may occasionally be wrong or incomplete.

Verify anything that matters

Before you rely on a result for something important, check it independently. That applies to homework and exams, where your institution's own methods are what count, and it applies with even more force to financial, scientific, medical, and engineering decisions. If an answer would be costly to get wrong, do not take it from GraphCalc alone.

Not professional advice

Nothing on GraphCalc, including the guides and worked examples, is professional advice of any kind. The real-world examples used to explain the mathematics are illustrations, not recommendations. For advice specific to your situation, consult a qualified professional.

External links

Where we link to other websites for reference, we do so in good faith, but we have no control over their content and take no responsibility for it. A link is not an endorsement.

Limitation of liability

To the fullest extent permitted by law, GraphCalc and the people behind it accept no liability for any loss or damage that results from using the site or acting on its results. You use the tools at your own risk. This disclaimer works together with our Terms of Use.
