Tangent

What It Does

The Tan node calculates the tangent of an angle value (in radians). Unlike sine and cosine which range from -1 to 1, tangent can produce values from negative infinity to positive infinity, creating more extreme oscillations.

Inputs

Name	Description	Type	Required
Value	The angle in radians	Number	No

Outputs

Name	Description	Type
Value	The tangent of the input angle	Number

Tan Example

How to Use It

1. Drag the Tan node into your graph.

2. Connect a number to the "Value" input or use the default (0).

3. The output will be the tangent of the input angle.

4. Be aware that at certain values (like π/2, 3π/2, etc.), the output approaches infinity.

Tips

• The tangent function has vertical asymptotes at odd multiples of π/2 (±π/2, ±3π/2, etc.).

• For stable results, avoid angles too close to these asymptotes.

• The tangent is mathematically equivalent to sine/cosine.

• Sine: For a bounded oscillating value between -1 and 1.

• Cosine: For another bounded oscillating value with a 90° phase shift from sine.

Use Cases

• Sharp Transitions: Create dramatic, rapid changes in values.

• Non-linear Mapping: Transform linear inputs into non-linear outputs with steep changes.

• Mathematical Modeling: Implement specialized mathematical functions that require tangent calculations.
