The force between electric charges Two charged objects, of charge q and Q, separated by a distance r, exert a force on one another. The magnitude of this force is given by: where k is a constant: The direction of the force is toward the second object if the objects have opposite signs, and away from the second Matlab timeout. How to calculate the distance between a point and a line using the formula. Example 1.

8.2: Open and Closed Sets
In mathematics , open sets are a generalization of open intervals in the real line. In a metric space —that is, when a distance is defined—open sets are the sets that, with every point P , contain all points that are sufficiently near to P that is all points whose distance to P is less to some value depending on P. More generally, one defines open sets as the members of a given collection of subsets of a given set, collection that has the property of containing every union of its members, every finite intersection of its members, the empty set, and the whole set itself. A set in which such a collection is given is called a topological space , and the collection is called a topology. These conditions are very loose, and allow enormous flexibility in the choice of open sets. For example, every subset can be open the discrete topology , or no set can be open but the space itself and the empty set the indiscrete topology. In practice, however, open sets are usually chosen to provide a notion of nearness that is similar to that of metric spaces, without having a measure of distance defined.

It provides a simple, thorough survey of elementary topics, starting with set theory and advancing to metric and topological spaces, connectedness, and compactness. Topology is a large subject with several branches, broadly categorized as algebraic topology, point-set topology, and geometric topology. Books to Borrow.

A metric space is, essentially, a set of points together with a rule for saying how far apart two such points are: De nition 1. Matrix Methods and Differential Equations.
