COS function

PRO BASIC

The COS function in Jspreadsheet Formulas Pro is a mathematical function that allows you to calculate the cosine of a specific angle. The angle should be provided in radians, not degrees. Simply enter the angle into the function and it will return the cosine value. This is particularly useful for various calculations in fields like physics, engineering, and computer graphics.

Documentation

Returns the cosine of an angle provided in radians.

Syntax

COS(number)

Parameter	Description
`number`	A numeric value representing the angle in radians.

Behavior

The COS function calculates the cosine of the given angle. The angle should be provided in radians. Here are some common behaviors:

Empty cells: If the referenced cell is empty, the function typically returns 0 (interpreted as COS(0))
Text: The COS function cannot process text. If a text string is provided as an input, the function will return an error.
Booleans: If a Boolean value (TRUE or FALSE) is provided as input, the function will interpret TRUE as 1 and FALSE as 0, and it will compute the cosine of these values.
Errors: If the cell to which the COS function is applied contains an error, the function will also return an error.
Non-numeric values: The COS function expects a numeric value (in radians) as input. If a non-numeric value is provided, the function will return an error.

Common Errors

Error	Description
#VALUE!	This error is displayed when the input to the `COS` function is non-numeric, such as a text string.

Best practices

Always ensure that the input to the COS function is a numeric value. Providing a non-numeric value will result in an error.

Remember that the COS function expects input in radians. If you have an angle in degrees, you will need to convert it to radians before using the COS function.

Use error handling mechanisms to handle potential errors that might arise when the COS function is applied to a cell that contains non-numeric values or errors.

Avoid using the COS function on large ranges of cells to prevent slow down in the spreadsheet's performance.

Usage

A few examples using the COS function.

COS(0)            // Returns 1 — cosine of 0 radians
COS(PI())         // Returns -1 — cosine of π radians
COS(PI()/4)       // Returns approximately 0.707 — cosine of 45 degrees
COS(RADIANS(60))  // Returns 0.5 — converts 60° to radians first
