Calculate Tangent Values

Calculate tangent of angles in radians using the math:tan() function

Query
logscale
myvalue := 120
        | math:tan(myvalue, as=tangent_value)
Introduction

In this example, the math:tan() function is used to calculate the tangent of an assigned value of 120 (interpreted as radians).

Step-by-Step

  1. Starting with the source repository events.

  2. logscale
    myvalue := 120

    Assigns the value 120 to a field named myvalue. This creates a new field with a constant value that will be used for the tangent calculation.

  3. logscale
    | math:tan(myvalue, as=tangent_value)

    Calculates the tangent of the value in the myvalue field and returns the result in a new field named tangent_value. Note that the input value is interpreted as radians, not degrees.

  4. Event Result set.

Summary and Results

The query calculates the tangent of a fixed value of 120 radians. Since tangent is a periodic function with period π (approximately 3.14159), the result represents the equivalent angle within one period.

This query is useful for performing consistent trigonometric calculations across events, testing specific angle values in radians, or adding reference trigonometric values to existing data.
