Part
(Built-in Mathematica Symbol) expr[[i]] or Part[expr, i] gives the i\[Null]^th part of expr. expr[[-i]] counts from the end. expr[[i, j, ...]] or Part[expr, i, j, ...] is equivalent to expr[[i]][[j]] .... ...
PowerDistribution[k, a] represents a power distribution with domain parameter k and shape parameter a.
PrimePi
(Built-in Mathematica Symbol) PrimePi[x] gives the number of primes \[Pi] (x) less than or equal to x.
PrimeZetaP[s] gives prime zeta function P(s).
RamanujanTauTheta[t] gives the Ramanujan tau theta function \[Theta](t).
SechDistribution[\[Mu], \[Sigma]] represents the hyperbolic secant distribution with location parameter \[Mu] and scale parameter \[Sigma].
SelfLoopStyle is an option for GraphPlot and related functions that specifies how to draw self-loops that connect a vertex to itself.
Sign
(Built-in Mathematica Symbol) Sign[x] gives -1, 0, or 1 depending on whether x is negative, zero, or positive.
