In Tableau, the `COT`

function is a number function that calculates the cotangent of a given angle. The cotangent is a trigonometric function that relates the ratio of the length of the adjacent side to the length of the opposite side in a right triangle.

The syntax for the `COT`

function in Tableau is as follows:

```
COT(angle)
```

`angle`

is the angle in radians for which you want to calculate the cotangent.

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

function in Tableau:

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

Angle |
---|

0.0 |

1.2 |

2.7 |

3.14 |

To calculate the cotangent of the "Angle" column using the `COT`

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:

```
COT([Angle])
```

- Click "OK" to create the calculated field.

The calculated field, which utilizes the `COT`

function, will calculate the cotangent for each value in the "Angle" column.

The resulting dataset will be as follows:

Angle | Cotangent |
---|---|

0.0 | Undefined |

1.2 | 0.4931 |

2.7 | -0.1282 |

3.14 | -0.0031 |

In this example, the `COT`

function calculates the cotangent for each angle value in the "Angle" column. For instance, the cotangent of 0.0 radians is undefined since it corresponds to a right angle, the cotangent of 1.2 radians is approximately 0.4931, and so on.

Please note that the `COT`

function returns undefined for angles that correspond to vertical lines (multiples of pi/2), as the cotangent is infinite in those
