Introduction

In this example, the math:sinh() function is used to calculate the hyperbolic sine of a value, demonstrating how this hyperbolic function differs from regular trigonometric sine.

Example incoming data might look like this:

Step-by-Step

  1. Starting with the source repository events.

  2. logscale
    myvalue := 2.5

    Assigns the value 2.5 to a variable named myvalue for use in the hyperbolic calculation.

  3. logscale
    | math:sinh(myvalue, as=hyperbolic_sine)

    Calculates the hyperbolic sine of the value in the myvalue field and returns the result in a new field named hyperbolic_sine. The math:sinh() function computes the value using the formula (e^x - e^-x)/2, where e is Euler's number.

  4. Event Result set.

Summary and Results

The query is used to calculate hyperbolic sine values, which are important in various mathematical and physical applications.

This query is useful, for example, to analyze exponential growth patterns, solve differential equations, or process data in fields such as electrical engineering and physics where hyperbolic functions are commonly used.
