How-to Guide

Entry point: WPS Spreadsheet → select a target cell → formula bar

  1. Open WPS Spreadsheet and go to the worksheet where you want the result.
  2. Select the cell that should display the calculation result.
  3. Type = in the cell or in the formula bar.
  4. Type IMSIN( to begin the function.

Success Criteria

  • On-screen result: The target 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.

2. Fill in arguments with the correct syntax

Entry point: A cell already in formula-editing mode

  1. Enter a valid argument after IMSIN(.
  2. Use a complex-number string, a cell reference, or another expression that returns a complex number.
  3. Check that parentheses and separators are complete.
  4. Press Enter to confirm the formula.

Success Criteria

  • On-screen result: The cell shows a calculated result instead of raw formula text.
  • What you can do next: You can select the cell again and review the full formula in the formula bar.

3. Use IMSIN with cross-worksheet references

  2. Switch to the worksheet that contains the source value.
  3. Select the source cell to insert its reference.
  4. Close the parenthesis and press Enter to finish the calculation.

Success Criteria

  • On-screen result: The result cell returns a calculated value.
  • What you can do next: If the referenced cell changes, the result can update with it.

Tips While Using

  • Common mistake: Referencing the wrong worksheet or cell can produce an unexpected result.

4. Check automatic result updates

Entry point: A worksheet that already contains an IMSIN formula

  1. Find a result cell that already uses IMSIN.
  2. Change the referenced input cell or edit the input value in the formula.
  3. Watch whether the result cell refreshes automatically.
  4. If needed, review the formula again in the formula bar.

Success Criteria

  • On-screen result: The result updates after the input changes.
  • What you can do next: You can continue editing, copying, or filling the formula.

Tips While Using

  • Common mistake: If you replace the result cell with a fixed value, it will no longer recalculate.
