Integral Calculator

What it does

In mathematics, an integral assigns numbers to functions in a way that can describe displacement, area, volume, and other concepts that arise by combining infinitesimal data. Integration is one of the two main operations of calculus, with its inverse operation, differentiation, being the other.

Integrate a function in your browser. Indefinite and definite integrals, a graph, and a numerical fallback. No Mathway iframe.

Type a function of x. Get the antiderivative, or fill in bounds for a definite integral. The plot is the integrand — not an ad frame. An indefinite integral is a family of antiderivatives F(x) + C. A definite integral from a to b is the signed area, F(b) − F(a), when an antiderivative exists (fundamental theorem of calculus). Use sin(x) , e^x , sqrt(x) , 1/x , polynomials. Leave From/To blank for + C. Fill both for a number. If there is no elementary antiderivative, a Simpson numerical estimate is shown when the bounds are finite. The old page embedded Mathway.
