The **antiderivative calculator** allows to find antiderivative function, antiderivative integral or indefinite integral of a function using
integration properties and different calculation mechanisms online. The antiderivative calculator is able to do symbolic **antidifferentiation**.

The **inverse derivative calculator** allows to :

- Calculate one of antiderivatives of a polynomial
- Calculate antiderivatives of the usual functions
- Calculate antiderivatives of a addition
- Calculate antiderivatives of a subtraction
- Calculate antiderivatives of a rational fraction
- Calculate antiderivatives of composed functions
- Calculate a antiderivative using integration by parts
- Calculate a primitive using the table of usual antiderivatives

The antiderivative calculator allows to **integrate online** any polynomial.

For example, **to compute an antiderivative** of the polynomial following `x^3+3x+1`, you must enter
antiderivative_calculator(`x^3+3x+1;x`), after calculating the result
`(3*x^2)/2+(x^4)/4+x` is returned.

The antiderivative calculator is able **to calculate online** all **antiderivatives** of **usual functions** : sin, cos, tan, ln, exp, sh, th, sqrt (square root), and many more ...

So, to obtain an antiderivative of the cosine function with respect to the variable x, type, antiderivative_calculator(`cos(x);x`), result `sin(x)` is returned after calculation..

Integration is a linear function, using this property allows the function to get the required result.

For the **online calculation** of **antiderivative** of **function sum**,
simply type the mathematical expression that contains the sum, specify the variable and apply function .

For example, to calculate an antiderivative line of the sum of the following functions `cos(x)+sin(x)`type antiderivative_calculator(`cos(x)+sin(x);x`), after calculating the result `sin(x)-cos(x)` is returned.

**To calculate** **online** an **antiderivative** of a **difference** of
**function**, just input mathematical expression that contains the difference, specify variable and
apply function antiderivative_calculator.

For example, to calculate online an antiderivative of the difference of the following functions `cos(x)-2x` type antiderivative_calculator(`cos(x)-2x;x`), after calculating the result `sin(x)-x^2` is displayed.

To **find the antiderivative of a rational fraction**, the calculator will use its
decomposition into simple elements.

For example, to find a antiderivative of the following rational fraction `(1+x+x^2)/x` : you must enter antiderivative_calculator(`(1+x+x^2)/x;x`)

**To calculate** **online** an **antiderivative** of **composition of functions** of
the form u(ax+b), where u is a usual function, simply type mathematical expression that contains the function,
specify variable and apply function antiderivative_calculator.

For example, to calculate online an antiderivative of the following function `exp(2x+1)` you must enter antiderivative_calculator(`exp(2x+1);x`), after calculating the result `exp(2x+1)/2` is displayed.

For example, to calculate online an antiderivative of the following function `sin(2x+1)` you must enter antiderivative_calculator(`sin(2x+1);x`), to get the following result `-cos(2*x+1)/2`.

For calculation of some functions, calculator is able to use **integration by parts**. The formula used is as follows :
Let f and g be two continuous functions, `int(f'g)=fg-int(fg')`

For example, to calculate an antiderivative `x*sin(x)`, calculator uses the integration by parts, to get the result, you must enter antiderivative_calculator(`x*sin(x);x`), after calculation, result sin(x)-x*cos(x) is returned with steps and detailed calculations.

To **integrate a function**, the following **formulas** can be used and the usual **calculation rules** applied:

By applying the integration formulas and using the **table of usual antiderivatives**, it is possible to calculate many function antiderivatives integral.
These are the calculation methods used by the calculator to find the indefinite integral.

The antiderivative calculator allows to calculate an antiderivative online with detail and calculation steps.

This example shows how to use the **antiderivative calculator** to integrate sin (x) + x with respect to x, you must enter:

- antiderivative_calculator(`sin(x)+x;x`) or
- antiderivative_calculator(`sin(x)+x`), when there is no ambiguity about the variable of integration.
