Cyclotomic[n, x] gives the n\[Null]^th cyclotomic polynomial in x.
EventHandler[expr, {"event_1" :> action_1, "event_2" :> action_2, ...}] displays as expr, evaluating action_i whenever "event_i" occurs in connection with expr.
FactorialPower[x, n] gives the factorial power x (n). FactorialPower[x, n, h] gives the step-h factorial power x (n, h).
Filling
(Built-in Mathematica Symbol) Filling is an option for ListPlot, Plot, Plot3D, and related functions that specifies what filling to add under points, curves, and surfaces.
FixedPointList[f, expr] generates a list giving the results of applying f repeatedly, starting with expr, until the results no longer change.
LucasL
(Built-in Mathematica Symbol) LucasL[n] gives the Lucas number L_n.LucasL[n, x] gives the Lucas polynomial L_n (x).
Normal
(Built-in Mathematica Symbol) Normal[expr] converts expr to a normal expression, from a variety of special forms.
PadeApproximant[expr, {x, x_0, {m, n}}] gives the Padé approximant to expr about the point x = x_0, with numerator order m and denominator order n.PadeApproximant[expr, {x, ...
ReliefImage[array] generates a relief image of an array of height values.
RootSum
(Built-in Mathematica Symbol) RootSum[f, form] represents the sum of form[x] for all x that satisfy the polynomial equation f[x] == 0.
