BUILT-IN MATHEMATICA SYMBOL
DiracDelta
DiracDelta[x]
represents the Dirac delta function 
.
DiracDelta[x1, x2, ...]
represents the multidimensional Dirac delta function 
.
Details
- DiracDelta[x] returns
for all numeric x other than 
. - DiracDelta can be used in integrals, integral transforms, and differential equations.
- Some transformations are done automatically when DiracDelta appears in a product of terms.
- DiracDelta[x1, x2, ...] returns
if any of the 
are numeric and not 
. - DiracDelta has attribute Orderless.
- For exact numeric quantities, DiracDelta internally uses numerical approximations to establish its result. This process can be affected by the setting of the global variable $MaxExtraPrecision.
