# Arc Sine

## Overview

![The Arc Sine Node.](/files/ocwaQf2IiMjdVR2iLadA)

The **Arc Sine Node** takes a single **Float** value and returns its *arcsine*, in degrees (°) or radians (rad).

[**Scope**](/incari-studio/2024.1/toolbox/overview.md#scopes): **Project**, **Scene**, **Function**, **Prefab**.

## Attributes

![The Arc Sine Node Attributes.](/files/ou2XvafUH45iYydwwh9A)

| Attribute       | Type      | Description                                                                      |
| --------------- | --------- | -------------------------------------------------------------------------------- |
| `Is Degree`     | **Bool**  | Determines whether the `Output` value is given in degrees (°) or radians (rad).  |
| `Default Value` | **Float** | The default value of `Input`, if no value is provided in the `Input` **Socket**. |

## Inputs

| Input             | Type      | Description                                                           |
| ----------------- | --------- | --------------------------------------------------------------------- |
| *Pulse Input* (►) | **Pulse** | A standard **Input Pulse**, to trigger the execution of the **Node**. |
| `Input`           | **Float** | The value to calculate the *arcsine* of.                              |

## Outputs

| Output             | Type      | Description                                                                                                                            |
| ------------------ | --------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| *Pulse Output* (►) | **Pulse** | A standard **Output Pulse**, to move onto the next **Node** along the **Logic Branch**, once this **Node** has finished its execution. |
| `Output`           | **Float** | The *arcsine* of `Input`.                                                                                                              |
