The ACOSH function in Excel is used to return the inverse hyperbolic cosine of a number. The function is particularly useful in various scientific and engineering calculations. Here’s how to use the ACOSH function:
Syntax
ACOSH(number)
- number: This is the value for which you want to find the inverse hyperbolic cosine. It must be a number greater than or equal to 1.
Steps to Use ACOSH in Excel
- Select a Cell: First, click on the cell where you want the result to appear.
- Enter the Formula: Type `=ACOSH(` in the selected cell.
- Input the Number: After the open parenthesis, type the number or the cell reference that contains the number for which you want to calculate the inverse hyperbolic cosine. For example, if the number is in cell A1, type `A1`.
- Close Parenthesis and Press Enter: Type `)` to close the parenthesis and press Enter.
Example: `=ACOSH(1)`
- View the Result: The cell will now display the result of the ACOSH calculation.
Example
If you want to calculate the inverse hyperbolic cosine of 10, the formula you would enter in the cell would be:
=ACOSH(10)
This will return approximately 2.99322 as the output since ACOSH(10) is approximately 2.99322.
Notes
- The ACOSH function requires that the number argument be 1 or greater. If an invalid number is provided, Excel will return a `#NUM!` error.
- The function can handle both direct numeric inputs and references to cells containing numbers.
By following these steps, you should be able to effectively use the ACOSH function in your Excel spreadsheets.
