# Tangent

> Calculate the tangent of an angle in radians or degrees.

The **Tangent** action calculates the tangent of an angle.

## Inputs

| Input          | Type               | Required | Description                                      |
| -------------- | ------------------ | -------- | ------------------------------------------------ |
| **Angle**      | Number             | Yes      | The angle to evaluate.                           |
| **Angle Unit** | Radians or Degrees | Yes      | How to interpret **Angle**. Defaults to radians. |

## Outputs

| Output     | Type   | Description                     |
| ---------- | ------ | ------------------------------- |
| **Result** | Number | The tangent of the input angle. |

For example, `45` degrees returns approximately `1`.

<Note>
  Tangent is undefined at angles such as `90°` and `π / 2`. Floating-point
  arithmetic may return a very large finite value near those angles instead of
  an explicit error.
