Shapes that have reach infinity include a single point, a straight line, a full square, and; any convex set. The graph of ...
A vertex can reach a vertex (and is reachable from ) if there exists a sequence of adjacent vertices (i.e. a walk) which starts with and ends with . In an undirected graph, reachability between all pairs of vertices can be determined by identifying the connected components of the graph.
A given point of sail (beating, close reach, beam reach, broad reach, and running downwind) is defined in reference to the true wind—the wind felt by a stationary observer. The motive power , and thus appropriate position of the sails, is determined by the apparent wind : the wind relative to an observer on the sailing craft.
Earth's subsolar point occurs at the point where the upper culmination of the Sun reaches the point's zenith. At this point, which moves around the tropics throughout the year, the Sun is perceived to be directly overhead. We apply the previous equation, A = 90° − L + δ, in the following examples.
A tautochrone curve or isochrone curve (from Ancient Greek ταὐτό 'same' ἴσος 'equal' and χρόνος 'time') is the curve for which the time taken by an object sliding without friction in uniform gravity to its lowest point is independent of its starting point on the curve.

The extreme value theorem was originally proven by Bernard Bolzano in the 1830s in a work Function Theory but the work remained unpublished until 1930. Bolzano's proof consisted of showing that a continuous function on a closed interval was bounded, and then showing that the function attained a maximum and a minimum value.
