Mathematica offers multiple ways of plotting functions of one variable. These include ordinary plots, log plots, parametric plots, and polar plots.
StarGraph[n] gives the star graph with n vertices S_n.
FindEdgeCover[g] finds an edge cover of the graph g with a minimum number of edges.
IsomorphicQ[g, h] yields True if graphs g and h are isomorphic.
GridGraph[n, m] constructs an n*m grid graph, the product of paths on n and m vertices. GridGraph[p, q, r] constructs a p*q*r grid graph, the product of GridGraph[p, q] and a ...
Bicomponents[g] gives the biconnected components of the undirected graph g.
CirculantGraph[n, j] gives the circulant graph with n vertices and jump j C_n (j).CirculantGraph[n, {j_1, j_2, ...}] gives the circulant graph with n vertices and jumps j_1, ...
AcyclicQ[g] yields True if graph g is acyclic.
BipartiteQ[g] yields True if graph g is bipartite.
CliqueQ
(Combinatorica Package Symbol) CliqueQ[g, c] yields True if the list of vertices c defines a clique in graph g.
