Conjunction[expr, {a_1, a_2, ...}] gives the conjunction of expr over all choices of the Boolean variables a_i.

Element[x, dom] or x \[Element] dom asserts that x is an element of the domain dom. Element[{x_1, x_2, ...}, dom] asserts that all the x_i are elements of dom. Element[patt, ...

GraphPeriphery[g] gives the set of vertices with maximum eccentricity in the graph g.

Scale[g, s] represents graphics primitives g scaled by a factor s. Scale[g, s, {x, y, ...}] scales with the point {x, y, ...} kept fixed. Scale[g, {s_x, s_y, ...}, ...] ...

Specularity[s] is a graphics directive which specifies that surfaces of 3D graphics objects which follow are to be taken to have specularity s. Specularity[s, n] uses ...

VertexQ[g, v] yields True if v is a vertex in the graph g and False otherwise.

Some basic matrix operations. Transposing a matrix interchanges the rows and columns in the matrix. If you transpose an m×n matrix, you get an n×m matrix as the result. ...

Just as Mathematica allows you to define how expressions should be evaluated, so also it allows you to define how expressions should be formatted for output. The basic idea ...

Mathematica allows you to export graphics and sounds in a wide variety of formats. If you use the notebook front end for Mathematica, then you can typically just copy and ...

Unless f is a flat function, a pattern like f[x_,y_] stands only for instances of the function with exactly two arguments. Sometimes you need to set up patterns that can ...
