TextCell["string"] gives a text cell that can appear in a Mathematica notebook.TextCell["string", " style"] gives a text cell with the specified style.
TicksStyle is an option for graphics functions which specifies how ticks should be rendered.
Times
(Built-in Mathematica Symbol) x*y*z, x*y*z, or x y z represents a product of terms.
Timing
(Built-in Mathematica Symbol) Timing[expr] evaluates expr, and returns a list of the time in seconds used, together with the result obtained.
UndirectedGraphQ[g] yields True if the graph g is an undirected graph and False otherwise.
VectorQ
(Built-in Mathematica Symbol) VectorQ[expr] gives True if expr is a list or a one-dimensional SparseArray object, none of whose elements are themselves lists, and gives False otherwise. VectorQ[expr, ...
VertexLabeling is an option for GraphPlot and related functions which specifies whether labeling should be included by default for vertices in graphs.
WeierstrassHalfPeriods[{g_2, g_3}] gives the half-periods {\[Omega], \[Omega]^\[Prime]} for Weierstrass elliptic functions corresponding to the invariants {g_2, g_3}.
$OutputSizeLimit specifies the maximum size in bytes of expressions that will automatically be output in their entirety in a Mathematica notebook.
When you write a program in Mathematica, you should always try to set it up so that its parts are as independent as possible. In this way, the program will be easier for you ...
