Tan online

The calculator allows to use most of the **trigonometric functions**, it is possible to calculate the
**tan**,
the sine
and the cosine
of an angle through the functions of the same name..

The **trigonometric function tangent** noted **tan**,
allows to **calculate
the tangent of an angle online **, it is possible to use different angular units :

- radians wich is the angular unit by default,
- degrees or
- gradians.

- Calculation of the tangent
- Special tangent values
- tan(0)=0
- tan(pi/6)=`tan(pi/6)=sqrt(3)/3`
- tan(pi/4)=`tan(pi/4)=1`
- tan(pi/3)=`tan(pi/3)=sqrt(3)`
- tan(2*pi/3)=`tan(2*pi/3)=-sqrt(3)`
- tan(3*pi/4)=`tan(3*pi/4)=-1`
- tan(5*pi/6)=`tan(5*pi/6)=-sqrt(3)/3`
- tan(pi)=`tan(pi)=0`
- Derivative of tangent
- Antiderivative of tangent
- Properties of the tangent function

The **tangent calculator** allows through the tan function to
**calculate**
**online** the **tangent** of an angle in radians, you must first
select the desired unit by clicking on the options button calculation module.
After that, you can start your calculations.

To **calculate tangent online** of `pi/6`, enter
tan(pi/6), after calculation, the result
`sqrt(3)/3` is returned.

Note that the tangent function is able to recognize some special angles and make the calculations with special associated values in exact form.

To **calculate the tangent of an angle** in degrees, you must first select the desired unit
by clicking on the options button calculation module. After that, you can start your calculus.

To calculate tangent of 60, enter tan(60), after calculation, the restults `sqrt(3)` is returned.

To calculate the tangent of an angle in gradians, you must first select the desired unit by clicking on the options button calculation module. After that, you can start your calculus.

To calculate tangent of 50, enter tan(50), after computation, the result `1` is returned.

Note that the tangent function is able to recognize some special angles and do the calculus with special associated exact values.

The tangent admits some special values which the calculator is able to determine in exact forms. Here is the list of
the **special tangent values**:

The derivative of the tangent is equal to `1/cos(x)^2`.

The antiderivative of the tangent is equal to `-ln(cos(x))`.

The **tangent** function is an odd function, for every real x, `tan(-x)=-tan(x)`.
The consequence for the curve representative of the tangent function is that it admits the origin of the reference point as point of symmetry.

The tan trigonometric function to calculate the tangent of an angle in radians, degrees or gradians.

To differentiate function tangent online, it is possible to use the derivative calculator which allows the calculation of the derivative of the tangent function

The **derivative of tan(x)** is derivative(tan(x))=`1/cos(x)^2`

Antiderivative calculator allows to calculate an antiderivative of tangent function.

An **antiderivative of tan(x)** is antiderivative(tan(x))=`-ln(cos(x))`

The limit calculator allows the calculation of limits of the tangent function.

The **limit of tan(x)** is limit(tan(x))

The **inverse function of tangent** is the arctangent function noted arctan.

The graphing calculator is able to plot tangent function in its definition interval.
