Symbolic d/dx with every rule application shown — power, product, quotient, and chain rule — plus an interactive tangent-line explorer on a live graph.
Tip: use samples, upload, copy, download, and send-to actions inside the workspace where available.
Derivative Step Calculator is a free, browser-based tool that helps you get the job done quickly. Symbolic d/dx with every rule application shown — power, product, quotient, and chain rule — plus an interactive tangent-line explorer on a live graph. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.
Use this tool as the focused step in a larger browser-based workflow.
Review the preview, copy or download the result, and keep everything local in your browser.
Equation Step Solver: Solve linear equations, quadratics, and 2×2 systems with every step shown — discriminant, formula substitution, factored form, and a live graph of the roots.
Open toolStatistics Step Explainer: Descriptive statistics, correlation, and least-squares regression where every metric expands into its full worked calculation — with histogram, box plot, and scatter charts.
Open toolCurve Fitting Calculator: Least-squares line, parabola, exponential, geometric, and power curve fitting with full equation tables.
Open toolSupported: + - * / ^, sin cos tan, exp or e^x, ln, log (base 10), sqrt, constants pi and e. Implicit multiplication works: 3x, 2sin(x), (x+1)(x-2).
Teal: f(x). Amber: f′(x). Dashed red: tangent to f at x₀ — its slope equals f′(x₀). Gaps mean the function is undefined there.
Indented steps solve the inner pieces required by the step above them.
