Disk[{x, y}, r] is a two-dimensional graphics primitive that represents a filled disk of radius r centered at the point x, y. Disk[{x, y}] gives a disk of radius 1. Disk[{x, ...

FindClusters[{e_1, e_2, ...}] partitions the e i into clusters of similar elements. FindClusters[{e_1 -> v_1, e_2 -> v_2, ...}] returns the v_i corresponding to the e i in ...

Fit[data, funs, vars] finds a least-squares fit to a list of data as a linear combination of the functions funs of variables vars.

ForAll[x, expr] represents the statement that expr is True for all values of x. ForAll[x, cond, expr] states that expr is True for all x satisfying the condition cond. ...

FunctionExpand[expr] tries to expand out special and certain other functions in expr, when possible reducing compound arguments to simpler ones. FunctionExpand[expr, assum] ...

GraphicsComplex[{pt_1, pt_2, ...}, data] represents a graphics complex in which coordinates given as integers i in graphics primitives in data are taken to be pt_i.
