ComfyUI Node: Sinus

Sinus:

The DF_Sinus node is designed to compute the sine of a given value, providing flexibility in terms of input units and the option to compute the arcsine instead. This node is particularly useful for AI artists who need to incorporate trigonometric functions into their workflows, such as generating wave patterns or manipulating angles. By allowing inputs in both radians and degrees, and offering the ability to switch between sine and arcsine calculations, the DF_Sinus node ensures versatility and ease of use. This node simplifies complex mathematical operations, making it accessible even to those without a deep technical background.

Sinus Input Parameters:

value

This parameter represents the numerical input for which the sine or arcsine value will be calculated. It accepts floating-point numbers, allowing for precise trigonometric computations. The value can be in radians or degrees, depending on the setting of the type_ parameter.

type_

This parameter determines the unit of the input value. It can be set to either "RAD" for radians or "DEG" for degrees. When set to "DEG", the input value is automatically converted to radians before performing the sine or arcsine calculation. This flexibility ensures that you can work with the unit that is most convenient for your specific application.

arcSin

This boolean parameter specifies whether to compute the arcsine (inverse sine) of the input value. When set to True, the node calculates the arcsine; otherwise, it calculates the sine. This option allows you to easily switch between these two related trigonometric functions without needing to modify the input value or perform additional calculations.

Sinus Output Parameters:

FLOAT

The output of the DF_Sinus node is a single floating-point number representing the result of the sine or arcsine calculation. This value can be used in subsequent nodes or processes within your workflow, enabling you to build complex trigonometric operations with ease. The output is always in radians, regardless of the input unit.

Sinus Usage Tips:

• To calculate the sine of an angle given in degrees, set the type_ parameter to "DEG" to ensure the input is correctly converted to radians.
• Use the arcSin parameter to easily switch between calculating the sine and the arcsine of the input value, depending on your specific needs.
• Combine the DF_Sinus node with other trigonometric nodes, such as DF_Cosines and DF_Tangent, to perform comprehensive trigonometric analyses and manipulations.

Sinus Common Errors and Solutions:

ValueError: math domain error

• Explanation: This error occurs when the input value for the arcsine function is outside the valid range of -1 to 1. - Solution: Ensure that the input value for the arcsine calculation is within the range of -1 to 1. If necessary, normalize or constrain the input value before passing it to the node.

TypeError: a float is required

• Explanation: This error occurs when the input value is not a floating-point number.
• Solution: Verify that the input value is a valid floating-point number. If the input is coming from another node, ensure that it outputs a float.

Invalid type_ value

• Explanation: This error occurs when the type_ parameter is set to a value other than "RAD" or "DEG".
• Solution: Check the type_ parameter and ensure it is set to either "RAD" or "DEG". Correct any typos or invalid values.
