# Sine

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

The **Sine** action calculates the sine 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 sine of the input angle. |

For example, `90` degrees returns approximately `1`, as does `π / 2` radians.
Small floating-point differences are normal.
