This FAQ covers 3 common question types about the TAN function in WPS on Windows, including parameter format, result checking, and repeated use across cells.
FAQ
What should I do if the TAN function returns an error?
- Check whether the parameter is a valid number or a correct cell reference.
- Confirm that the formula is written as
=TAN(...)and that the parentheses are complete. - If the formula refers to another cell, check whether that referenced cell contains text, spaces, or an error value.
Why is the TAN result different from what I expected?
- Confirm that the input parameter is correct.
- Check whether the referenced range or referenced cell content was changed by mistake.
- If needed, open Insert Function again to review the syntax and parameter details, then adjust the formula.
How can I use the TAN function in multiple cells?
- Enter
=TAN(...)in one cell first. - Select that cell and move the pointer to the fill handle in the lower-right corner.
- Drag down or across to copy the formula to other target cells.
