This FAQ covers 3 common questions about parameter format, result interpretation, and repeated use across cells, plus a short glossary.
FAQ
What should I do if SIN returns a #VALUE! error?
- Check whether the referenced cell contains text, spaces, or non-numeric content.
- Confirm that the formula uses the correct equals sign, parentheses, and punctuation.
- Clean the source data if needed, then re-enter the formula or reference a numeric cell.
Why does the SIN result look different from what I expected?
- Confirm that the input value is in radians rather than degrees.
- Check whether the referenced cell points to the correct source value.
- Review the function syntax again and compare the parameter input carefully.
How do I use the SIN function in multiple cells?
- Enter the correct
=SIN(...)formula in the first target cell. - Select that cell and drag the fill handle across the range you want to calculate.
- After filling, check whether relative references behave as expected and switch to absolute references if needed.
