Banaw Lakandula (sometimes also Bunaw Lakandula), often referred to simply by his title Lakandula, and later baptised Carlos Lacandola, was the Lakan (paramount ruler) of the pre-colonial Philippine Kingdom of Tondo when the Spaniards first conquered the lands of the Pasig River delta in the 1570s.
Another common variation of the name is Gat Dula which at present times evolved into Gatdula. He is sometimes erroneously referred to as Rajah Lakandula, but the terms "Rajah" and "Lakan" have the same meaning, making the use of both "Rajah" and "Lakandula" at the same time redundant.
Along with Rajah Matanda and Rajah Sulayman, he was one of three Rajahs who played significant roles in the Spanish conquest of the kingdoms of the Pasig River delta in the early 1570s.
Over time, Lakandula's name has come to be written in several ways. However, according to the firsthand account written by Hernando Riquel,the royal notary who accompanied Miguel Lopez de Legazpi, the Lord of Tondo specifically identified himself as "Sibunao Lakandula, lord of the town of Tondo" when he went onboard Legazpi’s ship with the Lords of Manila on May 18, 1571. The lords of Manila introduced themselves as "Rajah Ache the Old and Rajah Soliman the Young, lords and principals of the town of Manila"
In mathematics, big O notation is used to describe 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.
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. A description of a function in terms of big O notation usually only provides an upper bound on the growth rate of the function. Associated with big O notation are several related notations, using the symbols o, Ω, ω, and Θ, to describe other kinds of bounds on asymptotic growth rates.
Big O notation is also used in many other fields to provide similar estimates.
