InterpolatingPolynomial (Built-in Mathematica Symbol)

InterpolatingPolynomial[{f_1, f_2, ...}, x] constructs an interpolating polynomial in x which reproduces the function values f_i at successive integer values 1, 2, ... of x. ...

InverseFunctions (Built-in Mathematica Symbol)

InverseFunctions is an option for Solve and related functions that specifies whether inverse functions should be used.

InverseSeries (Built-in Mathematica Symbol)

InverseSeries[s] takes the series s, and gives a series for the inverse of the function represented by s. InverseSeries[s, x] uses the variable x in the inverse series.

JacobiSymbol (Built-in Mathematica Symbol)

JacobiSymbol[n, m] gives the Jacobi symbol (n/m).

JoinForm (Built-in Mathematica Symbol)

JoinForm[type] is a graphics directive that specifies what type of joins should be used to connect segments of lines, tubes, edges, and related primitives.

LaplaceDistribution (Built-in Mathematica Symbol)

LaplaceDistribution[\[Mu], \[Beta]] represents a Laplace double-exponential distribution with mean \[Mu] and scale parameter \[Beta].

LeafCount (Built-in Mathematica Symbol)

LeafCount[expr] gives the total number of indivisible subexpressions in expr.

LengthWhile (Built-in Mathematica Symbol)

LengthWhile[list, crit] gives the number of continuous elements e_i starting at the beginning of list for which crit[e_i] is True.

LineGraph (Built-in Mathematica Symbol)

LineGraph[g] gives the line graph of the graph g.
