Big O notation

In mathematics, big O notation describes the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. It is a member of a larger family of notations that is called Landau notation, Bachmann–Landau notation (after Edmund Landau and Paul Bachmann), or asymptotic notation. In computer science, big O notation is used to classify algorithms by how they respond (e.g., in their processing time or working space requirements) to changes in input size. In analytic number theory, it is used to estimate the "error committed" while replacing the asymptotic size, or asymptotic mean size, of an arithmetical function, by the value, or mean value, it takes at a large finite argument. A famous example is the problem of estimating the remainder term in the prime number theorem.

Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation.

Canada (ⁱ/ˈkænədə/; French: [ka.na.da]) is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres (3.85 million square miles), making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains; about four-fifths of the country's population of 35 million people live near the southern border. The majority of Canada has a cold or severely cold winter climate, but southerly areas are warm in summer.

The land now called Canada has been inhabited for millennia by various Aboriginal peoples. Beginning in the 15th century, British and French colonies were established on the Atlantic coast, with the first establishment of a region called "Canada" occurring in 1537. As a consequence of various conflicts, the United Kingdom gained and lost territories within British North America until left, in the late 18th century, with what mostly geographically comprises Canada today. Pursuant to the British North America Act, on July 1, 1867, the colonies of Canada, New Brunswick, and Nova Scotia joined to form the autonomous federal Dominion of Canada. This began an accretion of provinces and territories to the self-governing Dominion to the present ten provinces and three territories forming modern Canada. In 1931, Canada achieved near total independence from the United Kingdom with the Statute of Westminster 1931, and full sovereignty was attained when the Canada Act 1982 removed the last remaining ties of legal dependence on the British parliament.

Ecclesiastical Province of Canada

The Ecclesiastical Province of Canada was founded in 1860 and is one of four ecclesiastical provinces in the Anglican Church of Canada. Despite its name, the province covers only the former territory of Lower Canada (i.e., southern and eastern Quebec), the Maritimes, and Newfoundland and Labrador (Ontario was split off as a separate province in 1913). There are seven dioceses in the province:

Provinces of the Anglican Church of Canada are headed by a Metropolitan, elected from among the province's diocesan bishops. This bishop then becomes Archbishop of his or her diocese and Metropolitan of the Province. The current Metropolitan of the Province of Canada is the Most Rev. Percy D. Coffin, Archbishop of Western Newfoundland.
