How-to Guide

1. Enter the ACOSH function

Entry path: Formula tab → Formula bar

Open WPS Spreadsheets and select the cell where you want to show the result.
Type = in the formula bar or directly in the cell.
Type ACOSH(.
Enter the parameter and close the parenthesis, for example =ACOSH(2).
Press Enter to confirm and show the result in the cell.

Success Criteria

Interface result: The cell shows a calculation result.
Next action: You can continue editing, copying, or filling the formula.

Tips While Using

Start the formula with =.
The parameter should be a valid number greater than or equal to 1.

2. Check function syntax hints

Entry path: Formula tab → Formula bar

Select the target cell.
Type =ACOSH(.
Check the syntax hint that appears.
Review the parameter requirement and example, then continue entering the formula.

Success Criteria

Interface result: A syntax hint appears after you enter the function name.
Next action: You can complete the parameter and finish the calculation.

Tips While Using

If no hint appears, check whether the function name and opening parenthesis were entered correctly.
For longer formulas, editing in the formula bar can make the full content easier to review.

3. Use a cross-worksheet reference

Entry path: Formula tab → Formula bar

In the result cell, type =ACOSH(.
Switch to the worksheet that contains the source data.
Select the cell you want to reference.
Close the parenthesis and press Enter.

Success Criteria

Interface result: The formula includes a reference to a cell on another worksheet.
Next action: When the referenced cell changes, the result can update accordingly.

Tips While Using

The referenced cell value should meet the function parameter requirement.
If the worksheet name is complex, check that the reference format is complete.

4. Build a nested calculation

Entry path: Formula tab → Formula bar

Select the target cell and type =.
Enter the outer or inner function first.
Insert ACOSH() in the appropriate position.
Check that the parentheses and parameters are complete.
Press Enter to finish the calculation.

Success Criteria

Interface result: The formula returns a result without a syntax error.
Next action: You can continue adjusting the nesting level or replacing referenced cells.

Tips While Using

Make sure parentheses are paired correctly.
For multi-layer formulas, check parameters step by step.
