Calculate Sine of a Value

Compute trigonometric sine using the math:sin() function

Query
logscale
myvalue := 345
| math:sin(myvalue, as=mathvalue)
Introduction

In this example, the math:sin() function is used to calculate the sine of a positive value, demonstrating how the function handles standard input.

Step-by-Step

  1. Starting with the source repository events.

  2. logscale
    myvalue := 345

    Assigns the positive value 345 to a variable named myvalue for use in subsequent calculations.

  3. logscale
    | math:sin(myvalue, as=mathvalue)

    Calculates the sine of the value in the myvalue field and returns the result in a new field named mathvalue. The math:sin() function automatically handles the conversion of the input value to radians and returns a value between -1 and 1.

  4. Event Result set.

Summary and Results

The query is used to calculate the sine of a positive angle value, demonstrating basic trigonometric calculations.

This query is useful, for example, to analyze periodic data, process angular measurements, or calculate wave functions in scientific applications.

Sample output from the incoming example data:

mathvalue
-0.9589243

Note that the sine value for 345 radians is the exact opposite of the sine of -345 radians, demonstrating the odd symmetry property of the sine function where sin(-x) = -sin(x).
