When using ACOT, users usually ask about 3 issue types: formula errors, unexpected results, and applying the formula across multiple cells; this section answers 3 common questions.

FAQ

What should I do if ACOT returns #VALUE!?

  1. Check whether the parameter is numeric and make sure the referenced cell does not contain text, spaces, or other non-numeric characters.
  2. If the data was pasted from another source, clean the content and then enter the formula again.
  3. Confirm that the formula uses standard English punctuation for separators, then press Enter again.

Why does the ACOT result look different from what I expected?

  1. Check whether the referenced cell or range is correct.
  2. Confirm that the returned value is in radians, and convert it if you need a degree-based result.
  3. Review the formula step by step with the available formula-checking tools in WPS Spreadsheets.

How can I use ACOT in multiple cells at once?

  1. Enter the correct ACOT formula in the first target cell.
  2. Select that cell and drag the fill handle from the lower-right corner across the target range.
  3. If you need to lock a reference, add $ to the reference before filling the formula.
