COTH Function (LibreOffice Calc)

Math Beginner LibreOffice Calc

Learn the COTH function in LibreOffice Calc: Returns the hyperbolic cotangent of a number.

The COTH function in LibreOffice Calc is used for this task: Returns the hyperbolic cotangent of a number. Evaluate the hyperbolic cotangent of one.

This guide explains how to read the formula, reproduce a concrete example, interpret its result and recognize common input mistakes.

Syntax and arguments

COTH(number)
Argument Required? Meaning
Number Yes A value not equal to 0 for which the hyperbolic cotangent is to be returned.

Calc formulas normally use semicolons (;) between arguments in common configurations; the displayed separator may depend on settings or locale.

Worked example

=COTH(1)

Expected result: 1.3130353.

Why it works: Evaluate the hyperbolic cotangent of one. For decimal results, display formatting can change how many digits appear without changing the underlying number.

How to use it in your own spreadsheet

  1. Identify the cells or inputs that correspond to the sample values above.
  2. Enter the formula in an empty cell, changing the references or literal values to match your sheet.
  3. Compare the output with a manual check on a small known example.
  4. Extend the formula to a larger dataset only after you understand the result.

Common problems and practical checks

  • Check the accepted numeric domain, units and array dimensions for the specific operation.
  • If an error appears, check that the function arguments are of the expected type.
  • A pasted formula may produce an error when it uses the other program’s argument separator or unsupported options.
