# Getting tangent and hyperbolic tangent in Julia – tan(), tanh() and tand() Methods

The `tan()` is an inbuilt function in julia which is used to calculate tangent of the specified radian values.

Syntax: tan(x)

Parameters:

• x: Specified radian values.

Returns: It returns the calculated tangent of the specified radian values.

Example:

 `# Julia program to illustrate ``# the use of tan() method`` ` `# Getting tangent of the specified``# radian values.``println(tan(``0``))``println(tan(``30``))``println(tan(``90``))``println(tan(``44``))`

Output:

```0.0
-6.405331196646276
-1.995200412208242
0.017704699278685777```

The `tanh()` is an inbuilt function in julia which is used to calculate hyperbolic tangent of the specified values.

Syntax: tanh(x)

Parameters:

• x: Specified values.

Returns: It returns the calculated hyperbolic tangent of the specified values.

Example:

 `# Julia program to illustrate ``# the use of tanh() method`` ` `# Getting hyperbolic tangent``# of the specified values.``println(tanh(``0``))``println(tanh(``70``))``println(tanh(``90``))``println(tanh(``45``))`

Output:

```0.0
1.0
1.0
1.0```

The `tand()` is an inbuilt function in julia which is used to calculate tangent of the specified value in degrees.

Syntax: tand(x)

Parameters:

• x: Specified value in degrees.

Returns: It returns the calculated tangent of the specified value in degrees.

Example:

 `# Julia program to illustrate ``# the use of tand() method`` ` `# Getting tangent of the specified value ``# in degree``println(tand(``0``))``println(tand(``30``))``println(tand(``90``))``println(tand(``45``))`

Output:

```0.0
0.5773502691896258
Inf
1.0```
