ComfyUI Node: Tangent

Tangent:

The DF_Tangent node is designed to compute the tangent of a given angle, providing a crucial mathematical function for various applications in AI art and graphics. This node can handle both radians and degrees, making it versatile for different use cases. Additionally, it offers the option to compute the arctangent, which is the inverse of the tangent function. This flexibility allows you to perform a wide range of trigonometric calculations, enhancing your ability to manipulate and transform data in creative ways. Whether you are working on geometric transformations, animations, or other artistic effects, the DF_Tangent node provides a reliable and efficient way to incorporate trigonometric functions into your workflow.

Tangent Input Parameters:

value

This parameter represents the angle for which the tangent or arctangent is to be calculated. It accepts a floating-point number, which can be specified in either radians or degrees depending on the type_ parameter. The value of this parameter directly impacts the result of the tangent or arctangent computation.

type_

This parameter determines the unit of the angle provided in the value parameter. It can be set to either "RAD" for radians or "DEG" for degrees. The choice of unit affects how the input value is interpreted and subsequently converted for the trigonometric calculation. The available options are "RAD" and "DEG".

arcTan

This boolean parameter specifies whether to compute the arctangent (inverse tangent) instead of the tangent. If set to True, the node will calculate the arctangent of the input value. If set to False, it will compute the tangent. This parameter allows you to switch between the two related trigonometric functions based on your specific needs.

Tangent Output Parameters:

FLOAT

The output of the DF_Tangent node is a single floating-point number representing the result of the tangent or arctangent calculation. This value can be used in subsequent nodes or processes to achieve the desired mathematical or artistic effect. The output is crucial for tasks that require precise trigonometric computations.

Tangent Usage Tips:

• To compute the tangent of an angle in degrees, set the type_ parameter to "DEG" and provide the angle in the value parameter.
• If you need the arctangent of a value, ensure the arcTan parameter is set to True.
• Use the output of this node to drive transformations or animations that rely on trigonometric functions for smooth and realistic effects.

Tangent Common Errors and Solutions:

"ValueError: math domain error"

• Explanation: This error occurs when the input value for the arctangent function is outside the valid range.
• Solution: Ensure that the input value for the arctangent is within the valid range for the function. For the tangent function, ensure the input value is appropriate for the chosen unit (radians or degrees).

"TypeError: unsupported operand type(s)"

• Explanation: This error occurs when the input parameters are not of the expected type.
• Solution: Verify that the value parameter is a floating-point number and that the type_ and arcTan parameters are set to valid options ("RAD", "DEG" for type_ and True, False for arcTan).
