1. Open WPS Spreadsheet and select the cell where you want to display the result.
2. Type = in the formula bar or directly in the cell.
3. Continue by typing COT(.
4. Confirm that the worksheet is in formula entry mode and get ready to enter the argument.

Success Criteria

• Interface result: The selected cell enters formula editing mode.
• What you can do next: You can continue entering the argument and complete the formula.

Tips While Using

• Common mistake: If you do not start with =, the content may be treated as plain text.
• Environment note: Use an editable worksheet.

2. Fill in the argument correctly

Entry path: Select the target cell → formula bar

1. Enter the required argument after COT(.
2. Check the syntax prompt shown in the interface.
3. Type the closing parenthesis to complete the formula.
4. Press Enter to confirm the calculation.

Success Criteria

• Interface result: The cell displays the calculated result.
• What you can do next: You can copy the formula or revise the argument.

Tips While Using

• Common mistake: Unmatched parentheses or incorrect separators can cause a formula error.
• Environment note: The argument should meet the function requirements.

3. Use COT in a cross-sheet formula

Entry path: Target cell → formula bar

1. Open the workbook that contains the source data.
2. In the result cell, start a formula with =COT(.
3. Insert a reference to a cell on another worksheet as the argument.
4. Complete the formula and press Enter.

Success Criteria

• What you can do next: You can change the source data on another sheet and observe the updated result.

Tips While Using

• Common mistake: Referencing the wrong sheet or cell affects the result.
• Environment note: The referenced worksheet must be accessible in the current workbook.

4. Check nested formulas and automatic recalculation

Entry path: Formula bar

1. Add another function or reference expression around COT or inside its argument.
2. Complete the nested formula and press Enter.
3. Change the original data in a referenced cell.
4. Check whether the result updates automatically.

Success Criteria

• Interface result: The formula result updates when the source data changes.
• What you can do next: You can refine the formula structure or copy it to other cells.

Tips While Using

• Common mistake: It is easy to miss parentheses when the nesting level becomes deeper.
