delta

Description

 The names Δ and δ may refer to any of several distinct mathematical quantities.
 • For partial differentiation, see diff.
 • For the Dirac delta function, see Dirac.
 • For the Kronecker delta tensor in physics, see Physics[KroneckerDelta].
 • For the Kronecker delta tensor in differential geometry, see DifferentialGeometry[Tensor][KroneckerDelta].
 • For the Delta polynomial in differential algebra, see DifferentialAlgebra[Tools][DeltaPolynomial].
 • For the risk measure Delta under the Black-Scholes model, see Finance[BlackScholesDelta].

Examples

 > $\mathrm{diff}\left(f\left(x,y\right),x\right)$
 $\frac{{\partial }}{{\partial }{x}}\phantom{\rule[-0.0ex]{0.4em}{0.0ex}}{f}{}\left({x}{,}{y}\right)$ (1)
 > $\mathrm{int}\left(\mathrm{Dirac}\left(x\right)f\left(x\right),x=-\mathrm{\infty }..\mathrm{\infty }\right)$
 ${f}{}\left({0}\right)$ (2)
