DirectedInfinity[] represents an infinite numerical quantity whose direction in the complex plane is unknown. DirectedInfinity[z] represents an infinite numerical quantity ...
EulerE
(Built-in Mathematica Symbol) EulerE[n] gives the Euler number E_n. EulerE[n, x] gives the Euler polynomial E_n (x).
FillingStyle is an option for ListPlot, Plot, Plot3D, and related functions that specifies the default style of filling to be used.
FittedModel[...] represents the symbolic fitted model obtained from functions like LinearModelFit.
FixedPoint[f, expr] starts with expr, then applies f repeatedly until the result no longer changes.
InterpolatingFunction[domain, table] represents an approximate function whose values are found by interpolation.
InterpolationOrder is an option for Interpolation, as well as ListLinePlot, ListPlot3D, ListContourPlot, and related functions, that specifies what order of interpolation to ...
