<mo>

Use ∂ with the operand structure shown in the examples. Preserve grouping, limits, spacing, and evaluation order when converting between formats.

Characters to distinguish

  • ∇ — Nabla
  • ∫ — Integral

Meaning and usage

Denotes differentiation with respect to one variable while other variables are held fixed.

Used for multivariable functions, fields, and partial differential equations.

Pronunciation: partial derivative

Formula examples

\frac{\partial f}{\partial x}
\partial_t u

How to type Partial Derivative

Windows
Use Character Map or enter U+2202 in a Unicode-aware app.
macOS
Open Character Viewer with Control–Command–Space and search by name.
Microsoft Word
Type \partial in an equation and press Space.
iPhone and iPad
Copy and paste ∂, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
Android
Copy and paste ∂, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
Google Docs
For plain text, paste ∂ or use Insert → Special characters. For structured math, use the equation editor and verify \partial.
Excel
Paste ∂ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.

Common mistakes

  • Check whether ∂ is acting as an operator, differential, index, or variable in the surrounding expression; Used for multivariable functions, fields, and partial differential equations.
  • For plain text, copy ∂ as U+2202; for structured equations, use \partial in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Partial Derivative.

When to use ∂

  • Use ∂ in plain text when a Unicode character is appropriate and the destination preserves U+2202.
  • Use \partial in an equation editor when mathematical spacing or structure matters.
  • Define the local meaning when Partial Derivative is used in calculus, differential equations, tensor calculus with a field-specific convention.

Look-alikes and related characters

  • ∇ — Nabla
  • ∫ — Integral

Font and compatibility notes

Glyph shape can vary by font. Verify the code point after copying, and prefer LaTeX or MathML for structured equations.

Continue the workflow

From Partial Derivative to a finished equation

  1. Copy the characterUse ∂ in plain text when Unicode is accepted.
  2. Choose a structured formatUse \partial for LaTeX or the MathML snippet for accessible web equations.
  3. Edit or convertOpen the value in the editor or converter without retyping it.
