\partial is the rounded d of partial differentiation, always written inside a fraction with \frac. Ordinary derivatives use a plain d. The physics package's \pdv{f}{x} shortens the fraction form in full documents.
All ways to write it
| Command | Use | Package | Copy |
|---|---|---|---|
\partial | the curly d | none | |
\frac{\partial f}{\partial x} | first partial | none | |
\frac{\partial^2 f}{\partial x \partial y} | mixed second partial | none | |
\frac{d y}{d x} | ordinary derivative | none |
Example
\nabla f = \left( \frac{\partial f}{\partial x}, \frac{\partial f}{\partial y} \right)The gradient written out in partials.
Questions
How do I write a derivative evaluated at a point?
\left. \frac{\partial f}{\partial x} \right|_{x=0} — the \left. gives an invisible left delimiter so the bar scales.

Using partial derivative in Confluence
Confluence Cloud has no built-in LaTeX. With LaTeX Math for Confluence you add a math macro to any page, type \partial and it renders inline or as a block, with a live preview while you edit. Every command on this page renders there without extra packages.
