Derivative Calculator

The idea for Derivative Calculator was born out of frustration. Back when I was studying calculus, I often found myself stuck on complex differentiation problems. I had the textbook answers, but I didn't understand the process . Most online calculators were either behind a paywall, riddled with ads, or simply dumped the final result without explaining the "why." I wanted to build a tool that acts like a 24/7 tutor—one that doesn't just solve the problem but teaches you the methodology, specifically focusing on the Chain Rule, Product Rule, and Quotient Rule.
