VertexLabels is an option and property for Graph and related functions that specifies what labels and label positions should be used for vertices.

If you make a definition such as f[x_]:=value, Mathematica will use the value you give for any f function it encounters. In some cases, however, you may want to define a ...

The execution of a Mathematica program involves the evaluation of a sequence of Mathematica expressions. In simple programs, the expressions to be evaluated may be separated ...

InverseFourierCoefficient[expr, n, t] gives the function of t whose Fourier exponential series representation has coefficients given by expr, where expr is a function of n.

FactorList[poly] gives a list of the factors of a polynomial, together with their exponents.

Inverse[m] gives the inverse of a square matrix m.

ButterflyGraph[n] returns the n-dimensional butterfly graph, a directed graph whose vertices are pairs (w, i), where w is a binary string of length n and i is an integer in ...

The ability to define and use your own functions is part of what gives Mathematica such power. It is often inconvenient to have to explicitly name a function for every small ...

ArcCoth[z] gives the inverse hyperbolic cotangent coth -1 (z) of the complex number z.

EllipticLog[{x, y}, {a, b}] gives the generalized logarithm associated with the elliptic curve y^2 = x^3 + a x^2 + b x.
