When using ACOS, the most common questions involve input errors, result interpretation, and batch filling; this section answers 3 frequent questions.
FAQ
What should I do if ACOS returns an error?
- Check whether the parameter is numeric instead of text or a value with extra spaces.
- Confirm that the formula format is correct and that the parentheses are complete.
- Clean the source data if needed, and then enter the formula again.
Why does the ACOS result look different from what I expected?
- Check whether the referenced cell is correct.
- Confirm that the returned result is in radians rather than degrees.
- If you need degrees, continue with a degree conversion function in the next step.
How can I use ACOS in multiple cells?
- Enter and confirm the formula in the first cell.
- Select the cell and drag the fill handle across the target range.
