KelvinKei[z] gives the Kelvin function kei(z).KelvinKei[n, z] gives the Kelvin function kei_n (z).
KelvinKer[z] gives the Kelvin function ker(z).KelvinKer[n, z] gives the Kelvin function ker_n (z).
MachinePrecision is a symbol used to indicate machine-number precision.
DiscreteDelta[n_1, n_2, ...] gives the discrete delta function \[Delta] (n_1, n_2, ...), equal to 1 if all the n_i are zero, and 0 otherwise.
Hypergeometric0F1[a, z] is the confluent hypergeometric function \[Null]_0 F_1 (; a; z).
PageRankCentrality[g, \[Alpha]] gives a list of page-rank centralities for the vertices in the graph g and weight \[Alpha].PageRankCentrality[g, \[Alpha], \[Beta]] gives a ...
ArcTan
(Built-in Mathematica Symbol) ArcTan[z] gives the arc tangent tan -1 (z) of the complex number z. ArcTan[x, y] gives the arc tangent of y/x, taking into account which quadrant the point (x, y) is in.
lhs := rhs assigns rhs to be the delayed value of lhs. rhs is maintained in an unevaluated form. When lhs appears, it is replaced by rhs, evaluated afresh each time.
