InverseLaplaceTransform[expr, s, t] gives the inverse Laplace transform of expr. InverseLaplaceTransform[expr, {s_1, s_2, ...}, {t_1, t_2, ...}] gives the multidimensional ...
KroneckerDelta[n_1, n_2, ...] gives the Kronecker delta \[Delta] Subscript[n, 1] Subscript[n, 2] ..., equal to 1 if all the n_i are equal, and 0 otherwise.
NHoldAll is an attribute which specifies that none of the arguments to a function should be affected by N.
NumericFunction is an attribute that can be assigned to a symbol f to indicate that f[arg_1, arg_2, ...] should be considered a numeric quantity whenever all the arg_i are ...
Quotient[m, n] gives the integer quotient of m and n. Quotient[m, n, d] uses an offset d.
RealExponent[x] gives log_10 (|x|).RealExponent[x, b] gives log_b (|x|).
Signature[list] gives the signature of the permutation needed to place the elements of list in canonical order.
StudentTDistribution[\[Nu]] represents a Student t distribution with \[Nu] degrees of freedom.StudentTDistribution[\[Mu], \[Sigma], \[Nu]] represents a Student t distribution ...
$MaxPiecewiseCases gives the maximum number of cases to allow in explicit Piecewise objects generated by expanding any single piecewise function.
Attributes for controlling numerical evaluation. Usually N goes inside functions and gets applied to each of their arguments. This tells Mathematica not to apply N to the ...
