Mouseover[expr, over] represents an object that displays as over when the mouse pointer is over it, and as expr otherwise.

Or (Built-in Mathematica Symbol)

e_1 || e_2 || ... is the logical OR function. It evaluates its arguments in order, giving True immediately if any of them are True, and False if they are all False.

PermutationCycles (Built-in Mathematica Symbol)

PermutationCycles[perm] gives a disjoint cycle representation of permutation perm.

Scan (Built-in Mathematica Symbol)

Scan[f, expr] evaluates f applied to each element of expr in turn. Scan[f, expr, levelspec] applies f to parts of expr specified by levelspec.

SetSharedVariable (Built-in Mathematica Symbol)

SetSharedVariable[s_1, s_2, ...] declares the symbols s_i as shared variables whose values are synchronized among all parallel kernels.

Split (Built-in Mathematica Symbol)

Split[list] splits list into sublists consisting of runs of identical elements. Split[list, test] treats pairs of adjacent elements as identical whenever applying the ...

Sqrt (Built-in Mathematica Symbol)

Sqrt[z] or Sqrt[z] gives the square root of z.

StreamScale (Built-in Mathematica Symbol)

StreamScale is an option to StreamPlot, ListStreamPlot, and related functions that determines the length and arrowhead size of streamlines that are drawn.

$MachineEpsilon (Built-in Mathematica Symbol)

$MachineEpsilon gives the difference between 1.0 and the next-nearest number representable as a machine-precision number.

Algebraic Number Fields (Mathematica Tutorial)

Mathematica provides representation of algebraic numbers as Root objects. A Root object contains the minimal polynomial of the algebraic number and the root number—an integer ...
