## How do you use COS in Google Sheets?

COS is used in Google Sheets to calculate the cosine of a number. The COS function takes one argument, which is the angle in radians, and returns the cosine of that angle.

## What is the syntax of COS in Google Sheets?

The syntax of COS in Google Sheets is very simple. To use it, you just need to enter the following formula into a cell: =COS(number). This will return the cosine of the number you enter.

## What is an example of how to use COS in Google Sheets?

COS, or cosine, is a trigonometric function that can be used in Google Sheets to calculate the angle between two points. To use COS in Google Sheets, you'll need to create a custom formula. In the cell where you want the result to appear, type =COS( and then select the first cell in the range that contains the angle you want to calculate. Then, type ) and select the second cell in the range. Press ENTER to calculate the result.

## When should you not use COS in Google Sheets?

There are a few times when you should not use COS in Google Sheets. One instance is when you are trying to subtract two numbers and get a negative result. In this case, you would use the SIN function instead. Another time you should not use COS is when you are trying to calculate the square root of a number. In this case, you would use the SQRT function.

## What are some similar formulae to COS in Google Sheets?

There are a few similar formulae to COS in Google Sheets. One is SIN, which calculates the sine of a number. Another is TAN, which calculates the tangent of a number. These formulae can be used to calculate angles and other trigonometric values.
