About DerivCalc

DerivCalc is a free step-by-step derivative calculator built for students who want to understand differentiation, not just copy answers.

What it does

Type any function into the calculator and DerivCalc parses it, differentiates it symbolically, and shows every step of the work — with each rule named (power, product, quotient, chain, and more) and explained in one plain-English sentence. You can take derivatives up to the fifth order, evaluate the result at a point, graph the function alongside its derivative, and export a clean printable solution sheet for homework hand-ins.

Alongside the calculator, the worked solutions library covers the derivatives students search for most, each with a full walkthrough, the common mistakes to avoid, and practice problems.

Privacy by design

The entire differentiation engine runs in your browser. Nothing you type is sent to a server, no account is required, and the calculator keeps working offline once the page has loaded. Every answer is also verified numerically: the symbolic result is checked against a finite-difference estimate at several random points before you see a “verified” badge.

How the engine works

Under the hood, DerivCalc tokenizes your input, parses it into an expression tree, and walks that tree applying the standard differentiation rules — recording the name of each rule as it fires so the steps you see match the computation exactly. A simplifier then cleans up the result (collecting constants, cancelling ones and zeros) before rendering it as typeset math. There is no computer-algebra service behind it and no API call: the whole pipeline is a few hundred lines of dependency-free JavaScript.

Who builds it

DerivCalc is built and maintained by SilverCodeLabs, an independent developer studio making small, fast, single-purpose web tools and games. Questions, corrections, or feature requests are always welcome at hello@derivcalc.com.
