Which method should I use?
We recommend using the method marked as "Recommended" above. However, the best method depends on your specific needs:
- \nabla: Gradient (del) operator
Where do I use this symbol?
This symbol can be used:
- In mathematical equations (math mode)
- In regular text (if using text mode)
- In various document environments
Can I use this in display mode?
Yes, symbols that work in math mode (between $ $) also work in display mode (between $$ $$). This allows you to display the symbol on its own line with larger formatting.
