SIN (math/sin/float)

The SIN node calculates the sine of an input angle in radians and outputs the result as a float value between -1 and 1.

​
Inputs

  1. a (float, default: 0): The input angle in radians.

​
Outputs

  1. result (float): The sine of the input angle.

​
Configuration

This node has no additional configuration options.

​
Usage

To use the SIN node:
  1. Connect a float value representing an angle in radians to the a input port.
  2. The node will calculate the sine of the input angle and output the result via the result output port.

​
Example

Here’s an example of how to use the SIN node in a spell: 
{
  "nodes": [
    {
      "type": "math/sin/float",
      "id": "sinNode",
      "inputs": {
        "a": 1.5707963267948966
      }
    },
    {
      "type": "io/output/float",
      "id": "outputNode",
      "inputs": {
        "value": "@sinNode.result"
      }
    }
  ]
}
In this example:
  1. The sinNode is a SIN node with its a input set to 1.5707963267948966 (π/2 radians, or 90 degrees).
  2. The outputNode is connected to the result output of the sinNode.
When the spell is run, the SIN node will calculate the sine of π/2, which is approximately 1, and this value will be output by the outputNode.

​
Best Practices

  • Ensure that the input angle is in radians. If your angle is in degrees, convert it to radians before connecting it to the SIN node.
  • Keep in mind that the output of the SIN node will always be between -1 and 1, inclusive.

​
Common Issues

  • If the input angle is not in radians, the output will not be the expected value. Double-check that your input is in radians and convert from degrees if necessary.
  • No output or unexpected output may indicate that the input port is not properly connected. Verify that the a input port is connected to a valid float value.
