Trigonometry Functions

---

Description

The Trigonometry Functions processor performs trigonometric calculations on numerical values. It:

• Supports basic trigonometric functions (sin, cos, tan)
• Works with any numerical field type
• Preserves original event data
• Adds calculation results as new fields

---

Required Input

The processor requires an input event stream containing at least one numerical field to perform trigonometric calculations on.

---

Configuration

Alpha

Select the field from the input event that should be used as the angle (in radians) for the trigonometric calculation.

Operation

Choose one of the following trigonometric functions:

• sin: Calculates the sine of the angle
• cos: Calculates the cosine of the angle
• tan: Calculates the tangent of the angle

Output

The processor forwards the input event with an additional field named trigonometryResult containing the result of the trigonometric calculation.

Example

Input Event

{
  "angle": 1.57,
  "timestamp": 1586380105115
}

Configuration

• Alpha: angle
• Operation: sin

Output Event

{
  "angle": 1.57,
  "timestamp": 1586380105115,
  "trigonometryResult": 0.9999996829318346
}

Use Cases

1. Signal Processing

   • Waveform analysis
   • Signal filtering
   • Phase calculations
   • Frequency analysis

2. Geometric Calculations

   • Angle conversions
   • Distance calculations
   • Position tracking
   • Navigation systems

3. Scientific Computing

Notes

• Input angles must be in radians
• Results are stored as double-precision floating-point numbers
• The original event structure is preserved
• The calculation is performed for each incoming event
• The result field is always named trigonometryResult
