Step-by-step calculus

Calculus Calculator

Switch between integral, derivative and limit modes, set the parameters with the formula keyboard, and see every result with steps and a linked graph.

Learn the method

One expression, three ways to explore

Use the same function to connect its rate of change, accumulation and limiting behavior.

f(x)=x2,f′(x)=2x,∫03f(x) dx=9f(x)=x^2,\qquad f'(x)=2x,\qquad \int_0^3 f(x)\,dx=9
Calculus formulas

Worked example

  1. 1Choose Derivative for x² to obtain the slope function 2x.
  2. 2Choose Integral, set bounds 0 and 3, and obtain 9.
  3. 3Choose Limit and approach 2 to obtain 4 by continuity.

Switching modes changes the mathematical question. Check the variable, bounds and approach point before each calculation.

What this calculus calculator does

  • Integral, derivative and limit modes on one page for continuous work
  • Formula keyboard with fractions, roots, powers, trigonometric functions and constants
  • Parameter panel for the variable, bounds, order and limit direction
  • Results linked to an interactive graph: shaded areas, tangent lines and limit approach

How to use it

  1. Choose a mode: Integral, Derivative or Limit.
  2. Enter the expression with the keyboard or the Σ formula editor, then set the parameters.
  3. Press Calculate. Change the mode or parameters and calculate again without leaving the page.

Questions about the calculus calculator

What is the difference between this page and the solver pages?

The calculus calculator groups all three operations with explicit settings for continuous calculations. The dedicated pages open directly in one mode with examples for that topic.

Can I use the formula keyboard on a phone?

Yes. The formula editor shows a touch keyboard with fractions, roots, powers and trigonometric functions.

Does it show steps and graphs?

Yes. Every calculation includes the steps, a verification badge and a graph linked to the result.

Is my work saved?
