Mian Muhammad Asghar is a web developer based in Dubai, United Arab Emirates, with over 18 years of experience in educational technology. He has spent his career building free, accessible digital tools that help students learn — starting with OnlineCalculatorPlus.com in 2022 and later creating DerivativeCalculus.com in November 2025.
The idea for DerivativeCalculus.com came from a simple frustration: the best calculus calculators online — tools like Symbolab and Mathway — had hidden step-by-step solutions behind paywalls. Students who needed help the most were being asked to pay. Mian built DerivativeCalculus.com to fix that — a completely free, step-by-step derivative calculator with no sign-up, no paywall, and no limits.
Today, the platform is maintained by Mian and a growing community of mathematics educators, bloggers, and enthusiasts who voluntarily review content to ensure accuracy. What started as a solo project now reaches students in 150+ countries every month.

Our Mission: Free Calculus Help, For Every Student
DerivativeCalculus.com exists for one reason: to make high-quality calculus education completely free, for everyone, forever. No paywalls. No subscriptions. No sign-ups. Just clear, step-by-step math help — the kind that actually explains why an answer is correct, not just what the answer is.
We believe that your ability to learn calculus should not depend on how much money you have. Symbolab, Mathway, and other platforms have put their best features behind a paywall. We built this platform as a direct alternative — and we are committed to keeping it free forever.
🧠 Education-First Philosophy
Every tool we build is designed to help you understand calculus, not just get an answer. Step-by-step solutions explain each rule applied, so you learn while you solve.
🔍 Verification-First Accuracy
We don't rely on one person's authority. We use algorithmic cross-checking, community peer review, and cross-referencing with established textbooks to ensure every answer is correct.
🌍 Truly Global Reach
Students in 150+ countries use this platform every month — from AP Calculus students in the USA to engineering students across South Asia, Africa, and Europe.

Is DerivativeCalculus.com really free — forever?
Yes, completely and permanently free. All 30+ calculators, every step-by-step solution, all practice problems, the AI tutor (CalcMentor), and every learning resource on this site are available with no sign-up, no subscription, and no hidden fees. Unlike Symbolab and Mathway, we do not put step-by-step solutions behind a paywall. This is a founding commitment, not a promotional offer.
How accurate are the derivative calculators?
Our calculators achieve a
99.7% accuracy rate, maintained through a 4-layer verification system: (1) algorithmic cross-checking using MathJS and custom engines, (2) community peer review by mathematics educators, (3) public transparency logging of all corrections, and (4) cross-referencing with established textbooks including Stewart's Calculus and OpenStax Calculus. If you ever find an error, please
report it here — verified errors are corrected within 24 hours.
Who reviews the mathematical content?
Content is reviewed by a global collective of mathematics educators, graduate students, and computational experts. Our founder Mian Muhammad Asghar oversees the platform, and all significant content changes go through peer review before publishing. Every correction is publicly logged with a date and explanation — you can see this on our
Trust Methodology page. Our full editorial standards are published on our
