Students trust a math website only if the math is right. This page explains how we create, check, and update the calculators and guides on AntiderivativeCalculator.com.
Who Is Responsible
All calculators and articles are written or reviewed by Prof. Adrian Cole, a mathematics educator who focuses on calculus and integration. He is responsible for the accuracy of every page that carries his name.
How We Write Content
- Student first. We write in plain English at a level most high school students can read. We define each term before we use it.
- Standard notation. We use the notation found in common calculus textbooks, such as ∫ f(x) dx and d/dx.
- Worked examples. Every rule is shown with at least one full example and, where possible, a check.
- Trusted references. We compare our explanations with established sources, such as OpenStax Calculus, and link to them when useful.
- Tested examples. We use computer algebra software to test every worked example. A person reviews every page and every example before it is published.
How We Check the Math
- Every antiderivative in an article is checked by differentiating it.
- Every definite integral is checked with a numerical method.
- Each calculator is tested against a set of known problems before any update goes live.
- Calculator answers that cannot be verified automatically are not shown as verified.
Corrections
If you find an error, please contact us and choose “Error in an article” or “Calculator gave a wrong answer.” We aim to review reports within 2 business days. When we fix a meaningful error, we update the page and its “Last updated” date.
Independence
No company pays us to write about a product. If we ever publish sponsored content or show ads, they will be clearly labeled and will never change our explanations or results.
Updates
We review our most popular pages at least once a year to keep explanations clear and examples correct.
