Going into space is dangerous. A fair number of astronauts and cosmonauts have died during space missions and others have face with life-threatening situations. Astronauts go into space knowing that even a seemingly minor malfunction could prove fatal.
The key to math is Metric!!
How is the metric system use in America? How is the metric system use in Australia? How is the metric system use in Japan? How is the metric system use in Thailand? How is the metric system use in sweden? How is the metric system use in anywhere? Know the answer now?
Prove that if it were true then there must be a contradiction.
A topological space is simply a set, B, with topology t (see the related link for a definition), and is often denoted as B, t which is similar to how a metric space is often denoted; B, D.
prove that every metric space is hausdorff and first countable
In mathematics, a zero-dimensional topological space is a topological space that ... any point in the space is contained in exactly one open set of this refinement.
Cl is often used as shorthand for closure, e.g. if B, tis a topological space then Cl B is the closure of B. The closure of a topological space B, t is defined as the intersection of all of the closed sets containing B. The closure of C ⊂ B where B, D is a metric space is defined as all of the elements of B that have a 0 metric with C, written asCl C = {b Є B | D(b, C) = 0}.See related links.
The question doesn't make sense, or alternatively it is true by definition. A Hilbert Space is a complete inner product space - complete in the metric induced by the norm defined by the inner product over the space. In other words an inner product space is a vector space with an inner product defined on it. An inner product then defines a norm on the space, and every norm on a space induces a metric. A Hilbert Space is thus also a complete metric space, simply where the metric is induced by the inner product.

A Betti number is a number associated to each topological space and dimension, giving an approximate number of holes of that dimension in that space.
A compact metric space is not necessarily complete. Compactness only guarantees that every sequence in the space has a convergent subsequence, while completeness requires that every Cauchy sequence converges to a point in the space.
no
A family of subsets of the direct product of a topological space with itself that is used to derive a uniform topology for the space. Also known as uniform structure.
The wikipedia article says, 'The definition of a topological space relies only uponset theory and is the most general notion of a mathematical "space" that allows for the definition of concepts such as continuity, connectedness, and convergence.'These are abstract spaces where distance is, in some sense, ignored. When Euler considered the 'seven bridges of Koenigsberg problem', for instance, he appreciated that he was ignoring the distances between the bridges and was considering only how they were connected--so that someone could traverse each of them just once. Since that time, of course, the idea of a topological space has permeated many areas of mathematics.See the related link.
