The Integral Calculator lets you calculate integrals and antiderivatives of functions online — for free! Our calculator allows you to check your solutions to calculus exercises. It helps you practice by showing you the full working (step by step integration).
Free integral calculator - solve indefinite, definite and multiple integrals with all the steps. Type in any integral to get the solution, steps and graph
Enter the function you want to integrate into the editor. The Integral Calculator solves an indefinite integral of a function. You can also get a better visual and understanding of the function and area under the curve using our graphing tool.
Free Integral Calculator helps you solve definite and indefinite integration problems. Also double, triple and improper integrals. Answers, graphs, alternate forms.
x ln(u) + С. View solution steps. Find the integral of \log_ {e}\left (u\right) using the table of common integrals rule \int a\mathrm {d}x=ax. If F\left (x\right) is an antiderivative of f\left (x\right), then the set of all antiderivatives of f\left (x\right) is given by F\left (x\right)+C.
Calculator integrates functions using various methods: common integrals, substitution, integration by parts, partial fraction decomposition, trigonometric, hyperbolic, logarithmic identities and formulas, properties of radicals, Euler substitution, integrals of known forms, tangent half-angle substitution and Ostrogradsky's method.
The calculator is able to calculate the approximate integral. When the computer can not calculate the exact integral, it returns an approximate value of the integral. To determine the approximate value of an integral, the calculator uses the trapezoidal rule. Syntax : integral(function;value1;value2;variable) Examples :
