How-to Guide

1. Enter the IMCOS function

Entry point: Formulas tab → formula bar

1. Open AirSheet and select the cell where you want to enter the formula.
2. Type an equal sign (=) in the formula bar or directly in the cell.
3. Continue by typing IMCOS(.
4. Enter the correct argument and press Enter to display the result in the cell.

Success Criteria

• UI state: The cell shows the IMCOS calculation result.
• Next actions: You can continue editing the formula, copy it, or reference the result elsewhere.

Tips While Using

• Common mistakes: If you forget to type = first, the content may be treated as plain text.
• Environment limits: You need to work in an editable AirSheet cell.

2. View the function syntax prompt

Entry point: Formulas tab → formula bar

1. Select the target cell.
2. Type =IMCOS(.
3. Watch for the syntax prompt that appears automatically.
4. Review the argument requirement and example, then continue entering the formula.

Success Criteria

• UI state: After the function name is entered, you can see a prompt with argument guidance and an example.
• Next actions: You can complete the formula based on the prompt.

Tips While Using

• Common mistakes: If the function name is incomplete or misspelled, the prompt may not match correctly.
• Environment limits: You need to be in formula-entry mode to view the prompt.

3. Use cross-worksheet references or nested calculations in a formula

Entry point: Formulas tab → formula bar

1. Select the cell where you want the result to appear.
2. Start the formula with =IMCOS(.
3. Add a reference from another worksheet or nest another function inside the argument.
4. Check brackets and separators, then press Enter to complete the calculation.

Success Criteria

• UI state: The cell returns a formula result, and the full expression remains visible in the formula bar.
• Next actions: You can adjust the reference range or revise the nested structure.

Tips While Using

• Common mistakes: Unmatched brackets or missing separators can cause formula errors.
• Environment limits: The referenced worksheet and cells need to be accessible.

4. Update and review the calculation result

Entry point: Formulas tab → result cell

1. Change the source data referenced by the IMCOS formula.
2. Check whether the result cell updates automatically.
3. If needed, review the formula again and trigger recalculation through normal worksheet editing.
4. Confirm that the result matches your expectation.

Success Criteria

• UI state: When the source data changes, the result updates accordingly.
• Next actions: You can continue analyzing the result or copy it to other cells.

Tips While Using

• Common mistakes: If referenced cell content uses an unexpected format, the result may not match your expectation.
• Environment limits: In complex sheets, it helps to confirm the reference relationship first.
