Underflow[] represents a number too small to represent explicitly on your computer system.
UndirectedEdge[u, v] or u \[UndirectedEdge] v represents an undirected edge of a graph with vertices u and v.
BeniniDistribution[\[Alpha], \[Beta], \[Sigma]] represents a Benini distribution with shape parameters \[Alpha] and \[Beta] and scale parameter \[Sigma].
Nest
(Built-in Mathematica Symbol) Nest[f, expr, n] gives an expression with f applied n times to expr.
The Mathematica graphics language has many controls for preparing and laying out plots. Aligning plots is important when preparing graphics for presentation or publication.
Total
(Built-in Mathematica Symbol) Total[list] gives the total of the elements in list. Total[list, n] totals all elements down to level n. Total[list, {n}] totals elements at level n. Total[list, {n_1, n_2}] ...
ValueQ
(Built-in Mathematica Symbol) ValueQ[expr] gives True if a value has been defined for expr, and gives False otherwise.
DirectedEdge[u, v] or u \[DirectedEdge] v represents a directed edge from u to v.
WignerD
(Built-in Mathematica Symbol) WignerD[{j, m_1, m_2}, \[Psi], \[Theta], \[Phi]] gives the Wigner D-function D_m_1^m_2, j(\[Psi], \[Theta], \[Phi]).WignerD[{j, m_1, m_2}, \[Theta], \[Phi]] gives the Wigner ...
The first argument given to DSolve is the differential equation, the second argument is the unknown function, and the last argument identifies the independent variable. Here ...
