$FrontEnd (Built-in Mathematica Symbol)

$FrontEnd is a global variable that specifies to what front end object, if any, the kernel is currently connected.

$FrontEndSession (Built-in Mathematica Symbol)

$FrontEndSession is a global symbol that represents the current session of the front end from which the kernel is being run.

Global Options for the Front End (Mathematica Tutorial)

In the standard notebook front end, Mathematica allows you to set a large number of global options. The values of all these options are by default saved in a "preferences ...

GridLines (Built-in Mathematica Symbol)

GridLines is an option for two-dimensional graphics functions that specifies grid lines.

PolarGridLines (Built-in Mathematica Symbol)

PolarGridLines is an option for sector charts and polar plots that specifies polar grid lines.

Principal Axis Method (Mathematica Tutorial)

"Gauss–Newton" and "conjugate gradient" methods use derivatives. When Mathematica cannot compute symbolic derivatives, finite differences will be used. Computing derivatives ...

CompleteQ (Combinatorica Package Symbol)

CompleteQ[g] yields True if graph g is complete. This means that between any pair of vertices there is an undirected edge or two directed edges going in opposite directions.

EmptyGraph (Combinatorica Package Symbol)

EmptyGraph[n] generates an empty graph on n vertices. An option Type that can take on values Directed or Undirected is provided. The default setting is Type -> Undirected.

InDegree (Combinatorica Package Symbol)

InDegree[g, n] returns the in-degree of vertex n in directed graph g. InDegree[g] returns the sequence of in-degrees of the vertices in directed graph g.

NumberOfDirectedGraphs (Combinatorica Package Symbol)

NumberOfDirectedGraphs[n] returns the number of nonisomorphic directed graphs with n vertices. NumberOfDirectedGraphs[n, m] returns the number of nonisomorphic directed ...
