In Tableau, the `RADIANS`

function is a number function that converts an angle from degrees to radians. It returns the value of the angle expressed in radians.

The syntax for the `RADIANS`

function in Tableau is as follows:

```
RADIANS(angle)
```

`angle`

represents the angle in degrees that you want to convert to radians.

Here's an example to illustrate the usage of the `RADIANS`

function in Tableau:

Suppose you have a dataset with a column called "Angle" that contains different angle values in degrees.

Angle |
---|

45 |

90 |

180 |

270 |

To convert each angle in the "Angle" column from degrees to radians using the `RADIANS`

function, you can create a calculated field in Tableau:

- Right-click on a blank area in the "Data" pane in Tableau.
- Select "Create Calculated Field."
- In the formula editor, enter the following expression:

```
RADIANS([Angle])
```

- Click "OK" to create the calculated field.

The calculated field, which utilizes the `RADIANS`

function, will convert each angle in the "Angle" column from degrees to radians.

The resulting dataset will be as follows:

Angle | Radians |
---|---|

45 | 0.7854 |

90 | 1.5708 |

180 | 3.1416 |

270 | 4.7124 |

In this example, the `RADIANS`

function converts each angle in the "Angle" column from degrees to radians. For instance, the angle of 45 degrees is converted to approximately 0.7854 radians, the angle of 90 degrees is converted to approximately 1.5708 radians, and so on.

The `RADIANS`

function is commonly used in trigonometry and geometry calculations, where angles are often required to be in radians. By utilizing the `RADIANS`

function in Tableau, you can easily convert angles from degrees to radians and perform various mathematical operations involving angles.
