Fibonacci number. A tiling with squares whose side lengths are successive Fibonacci numbers In mathematics, the Fibonacci numbers or Fibonacci sequence are the numbers in the following integer sequence: or (often, in modern usage): (sequence A000045 in OEIS). The Fibonacci spiral: an approximation of the golden spiral created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling;[3] this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34. By definition, the first two numbers in the Fibonacci sequence are either 1 and 1, or 0 and 1, depending on the chosen starting point of the sequence, and each subsequent number is the sum of the previous two. In mathematical terms, the sequence Fn of Fibonacci numbers is defined by the recurrence relation with seed values or The Fibonacci sequence is named after Fibonacci.
Fibonacci numbers are closely related to Lucas numbers in that they are a complementary pair of Lucas sequences. Origins[edit] List of Fibonacci numbers[edit] and. Saudi Arabia. Saudi Arabia[b] ( i/ˌsaʊdi əˈreɪbi.ə/ or i/ˌsɔːdiː əˈreɪbi.ə/), officially known as the Kingdom of Saudi Arabia (KSA),[c] is the largest Arab state in Western Asia by land area (approximately 2,150,000 km2 (830,000 sq mi), constituting the bulk of the Arabian Peninsula) and the second-largest in the Arab world (after Algeria). It is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain and the United Arab Emirates to the east, Oman to the southeast, and Yemen in the south.
It is the only nation with both a Red Sea coast and a Persian Gulf coast. Etymology[edit] Following the unification of the kingdoms of Hejaz and Nejd, the new state was named al-Mamlakah al-ʻArabīyah as-Suʻūdīyah (a transliteration of المملكة العربية السعودية in Arabic) by royal decree on 23 September 1932 by its founder, Abdulaziz Al Saud (Ibn Saud). History[edit] Before the foundation of Saudi Arabia[edit] The Arabian Peninsula in 1914 Post-unification[edit] Cambodia. Cambodia ( i/kæmˈboʊdiə/;[8] Khmer: កម្ពុជា, Kampuchea, IPA: [kɑmˈpuˈciə]), officially known as the Kingdom of Cambodia (Khmer: ព្រះរាជាណាចក្រកម្ពុជា, Preăh Réachéanachâk Kâmpŭchéa) and once known as the Khmer Empire, is a country located in the southern portion of the Indochina Peninsula in Southeast Asia.
Its total landmass is 181,035 square kilometres (69,898 sq mi), bordered by Thailand to the northwest, Laos to the northeast, Vietnam to the east, and the Gulf of Thailand to the southwest. Cambodia's ancient name is "Kambuja" (Sanskrit: कंबुज).[10] In 802 AD, Jayavarman II declared himself king marking the beginning of the Khmer Empire which flourished for over 600 years allowing successive kings to dominate much of Southeast Asia and accumulate immense power and wealth.
The Indianized kingdom built monumental temples including Angkor Wat, now a World Heritage Site, and facilitated the spread of first Hinduism, then Buddhism to much of Southeast Asia. Name[edit] History[edit] Mormon (Book of Mormon) Mormon /ˈmɔrmən/ is believed by followers of Mormonism to have been the narrator of much of the Book of Mormon, a sacred text of the Latter Day Saint movement, which describes him as a prophet-historian and a member of a tribe of indigenous Americans known as the Nephites.
According to the Book of Mormon, the prophet Mormon engraved an abridgement of his people's history on golden plates. Based on the chronology described in the book, Mormon lived during the 4th century AD. As a narrator in the text, Mormon presents himself as a redactor. He quotes and paraphrases other writers, collects and includes whole texts by other authors, contributes running commentary, and also writes his own narrative. He writes about the process of making the book, both in terms of compiling the works of other prophets and also in terms of engraving the words on metal plates.
He alludes to content that is left out of the book, and refers to a larger collection of records at his disposal. Wikipedia.
