What this calculus solver does

  • Detects whether your problem is an integral, derivative or limit and solves it on this page
  • Every answer comes with numbered steps that name the rule used
  • Follow-up questions, graphs, practice quizzes and narrated video lessons for each problem
  • Photo input: snap or paste a picture of the problem and edit the recognised text before solving

How to use it

  1. Type or paste the problem, insert formulas with the Σ editor, or upload a photo.
  2. Press Solve. The answer streams in with the final result first, then the steps.
  3. Ask about any step, open the graph, generate a video lesson or practise with similar problems.

Questions about the calculus solver

Is this calculus solver free?

Currently, solving problems, viewing the steps, graphs and practice questions is free and does not require an account. Pricing and access may change in the future. Video lessons have a small daily allowance per network to keep costs under control.

Which calculus problems can it solve?

Indefinite and definite integrals (including improper integrals), first and higher-order derivatives, and finite, infinite and one-sided limits. Related problems such as tangent lines or series are handled on a best-effort basis.

How do I know the answer is correct?

Each answer is checked independently with numeric methods where possible: antiderivatives are differentiated back, derivatives are compared at sample points and limits are sampled from both sides. The badge next to the answer tells you whether the check passed, failed or could not run.

Do I need to install an app?

No. Everything runs in your browser on desktop and mobile. Your history, favourites, quizzes and videos are stored in this browser only; nothing is uploaded to an account.
