The partial derivative symbol denotes differentiation of a multivariable function with respect to one variable while holding the others constant — written ∂f/∂x. It is essential to multivariable calculus, thermodynamics and physics.
How to type Partial Derivative (∂)
- Fastest: click ∂ on the keyboard above — it copies to your clipboard, ready to paste into Word, Google Docs, email or a forum.
- Unicode: the code point is shown in the panel above; on Windows you can also use Alt‑X after the hex code in Word.
- LaTeX: use the command shown above inside math mode.
- Anywhere: because it’s standard Unicode, it keeps its exact form across apps and devices.
Frequently asked questions
How is ∂ different from d?
∂ is used when a function has several variables and you differentiate with respect to just one; d is for single‑variable derivatives.
Where is ∂ used?
Multivariable calculus, differential equations, thermodynamics and field theory.
