... S n−1 . Each vertex in ∂(sd([−1, 1]n )) is a vector in {−1, 1, 0}n \ {0}n . We denote such a vector by a signed set X, which is a pair X = (X + , X − ) of disjoint subsets X + , X − ⊆ [n], defined as X + = {i: X(i) = 1} and X − = {i: X(i) = −1}. Let |X| = |X + | + |X − |, and write X ≤ Y if X + ⊆ Y + ...

Graphing More General Tangent, Cotangent, Secant and Cosecant
... To quickly sketch the graphs of equations of the form y A tan (Bx C ), you need to know how the constants A, B, and C affect the basic graphs of y tan x and y cot x, respectively. First note that amplitude is not defined for the tangent and cotangent functions. The graphs of both deviate wit ...

Median graph
In graph theory, a division of mathematics, a median graph is an undirected graph in which every three vertices a, b, and c have a unique median: a vertex m(a,b,c) that belongs to shortest paths between each pair of a, b, and c.The concept of median graphs has long been studied, for instance by Birkhoff & Kiss (1947) or (more explicitly) by Avann (1961), but the first paper to call them ""median graphs"" appears to be Nebeský (1971). As Chung, Graham, and Saks write, ""median graphs arise naturally in the study of ordered sets and discrete distributive lattices, and have an extensive literature"". In phylogenetics, the Buneman graph representing all maximum parsimony evolutionary trees is a median graph. Median graphs also arise in social choice theory: if a set of alternatives has the structure of a median graph, it is possible to derive in an unambiguous way a majority preference among them.Additional surveys of median graphs are given by Klavžar & Mulder (1999), Bandelt & Chepoi (2008), and Knuth (2008).
