<!--The upper-case letter Δ is used as the symbol for:
* The [[difference operator]], affecting a change or difference between mathematical values:
:<math>{y_2-y_1\over x_2-x_1} = {\Delta y \over \Delta x} </math> = the average change of y per unit x
* The [[Laplace operator]]:
:<math>\Delta f = \frac {\partial^2 f}{(\partial x)^2} + \frac {\partial^2 f}{(\partial y)^2} </math>
* A [[derivative|macroscopic change]] in the value of a variable in mathematics or science.
* Any of the [[baryon|delta particles]] in particle physics.
 
The lower-case letter δ is used as the symbol for:
* A [[Differential (mathematics)|microscopic change]] in the value of a variable in mathematics or science.
* An auxiliary function in [[Calculus]] used to rigorously define the [[Limit of a function|limit]] or [[Continuous function|continuity]] of a given function.
* The [[Kronecker delta]] in mathematics.
* The [[Dirac delta function]] in mathematics.
* [[Deflection]] in engineering mechanics
* A mark for deletion in [[proofreading]]. The usage is said to date back to classical times.-->
