  2. Type = in the formula bar or directly in the cell.
  3. Type ATAN( to begin the function.
  4. Enter the value or cell reference to calculate.
  5. Type the closing parenthesis and press Enter to view the result.

Success Criteria

  • Interface result: the selected cell shows the ATAN calculation result.
  • What you can do next: you can copy the formula, change the argument, or fill it down.

Tips While Using

  • Common mistake: if you do not start with =, the content may be treated as plain text.
  • Environment note: the input should be a valid number or a valid cell reference.

2. View syntax guidance and fill in the argument

Entry point: select a cell and start typing the function

  1. Select the target cell.
  2. Type =ATAN(.
  3. Check the syntax guidance shown by the app.

  • What you can do next: you can complete the argument and finish the calculation based on the prompt.

Tips While Using

  • Common mistake: an unclosed parenthesis or an invalid argument format may prevent a normal result.
  • Environment note: for longer formulas, using the formula bar makes the full content easier to review.

3. Use ATAN in nested formulas or cross-worksheet references

Entry point: formula bar

  1. Select the cell where you want to return the result.
  2. Enter a combined formula that includes ATAN.
  3. Add other functions or cross-worksheet references as needed.
  4. Check the parentheses, references, and arguments.

Success Criteria

  • Interface result: the combined formula returns a normal result.
  • What you can do next: after referenced data changes, the result can update with the data.

Tips While Using

  • Common mistake: an incorrect cross-worksheet reference can affect the result.
  • Environment note: for longer nested formulas, check arguments and references step by step.
