Editorial Policy

Our Editorial Mission

We exist to provide free, accurate, and accessible calculus education to students everywhere. Whether you're just starting with derivatives or diving into advanced topics, our goal is to make learning clear and approachable. No corporate jargon, no paywalls — just math help you can trust.

How Our Content is Created

All content on DerivativeCalculus.com is created by our editorial team — a group of passionate educators, developers, and math enthusiasts. We write based on established mathematical principles, widely used textbooks, and curriculum standards like AP Calculus and common university syllabi. Every explanation is crafted in clear, student‑friendly language, because math shouldn't be harder to read than it is to solve.

How We Verify Accuracy

Accuracy is our top priority. Before any calculator or article goes live, it undergoes a multi‑step verification process:

• Algorithmic checks: Our calculators are tested against multiple computational engines (MathJS, SymPy, and custom algorithms) to ensure results match across methods.
• Community peer review: We invite mathematics educators and graduate students from our global community to review new content. This distributed review catches nuances that automated tools might miss.
• Pre‑publication review: Every article is read by at least two members of our editorial collective before it's published.
• User feedback loop: If you spot an error, you can report it via our contact page. Verified corrections are made within 24 hours and logged transparently.

Our Sources and References

We build our content on a foundation of trusted mathematical references, including:

• Stewart's Calculus (8th ed.)
• Thomas' Calculus (14th ed.)
• OpenStax Calculus (open‑source textbooks)
• Khan Academy's curriculum framework
• AP Calculus Course and Exam Description (College Board)

We never reproduce copyrighted content. When we reference external sources, we provide clear links or citations so you can explore further.

Updates and Corrections

We continuously improve our content. Whenever an error is found or curriculum standards evolve, we update the relevant page promptly. Major updates are noted with a "Last Updated" date at the top of each page. We believe in being transparent about changes — you can always see what was corrected and why.

Independence

DerivativeCalculus.com is an independent project. We are not funded by any institution, advertiser, or commercial entity. Our content decisions are driven solely by educational value — what helps students learn best. We do not accept sponsored content or paid placements, and we never will.
