Tolerance (Built-in Mathematica Symbol)

Tolerance is an option for various numerical options which specifies the tolerance that should be allowed in computing results.

Trace (Built-in Mathematica Symbol)

Trace[expr] generates a list of all expressions used in the evaluation of expr. Trace[expr, form] includes only those expressions which match form. Trace[expr, s] includes ...

TreeForm (Built-in Mathematica Symbol)

TreeForm[expr] displays expr as a tree with different levels at different depths. TreeForm[expr, n] displays expr as a tree only down to level n.

TrigExpand (Built-in Mathematica Symbol)

TrigExpand[expr] expands out trigonometric functions in expr.

Tr (Built-in Mathematica Symbol)

Tr[list] finds the trace of the matrix or tensor list. Tr[list, f] finds a generalized trace, combining terms with f instead of Plus. Tr[list, f, n] goes down to level n in ...

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, ...

VertexCoordinateRules (Built-in Mathematica Symbol)

VertexCoordinateRules is an option for GraphPlot and related functions which specifies rules for determining the coordinates at which vertices should be placed.

Which (Built-in Mathematica Symbol)

Which[test_1, value_1, test_2, value_2, ...] evaluates each of the test_i in turn, returning the value of the value_i corresponding to the first one that yields True.

$MaxExtraPrecision (Built-in Mathematica Symbol)

$MaxExtraPrecision gives the maximum number of extra digits of precision to be used in functions such as N.

$MessagePrePrint (Built-in Mathematica Symbol)

$MessagePrePrint is a global variable whose value, if set, is applied to expressions before they are included in the text of messages.
