Equation

In mathematics, an equation is an equality containing one or more variables. Solving the equation consists of determining which values of the variables make the equality true. In this situation, variables are also known as unknowns and the values which satisfy the equality are known as solutions. An equation differs from an identity in that an equation is not necessarily true for all possible values of the variable.

There are many types of equations, and they are found in many areas of mathematics. The techniques used to examine them differ according to their type.

Algebra studies two main families of equations: polynomial equations and, among them, linear equations. Polynomial equations have the form P(x) = 0, where P is a polynomial. Linear equations have the form a(x) + b = 0, where a is a linear function and b is a vector. To solve them, one uses algorithmic or geometric techniques, coming from linear algebra or mathematical analysis. Changing the domain of a function can change the problem considerably. Algebra also studies Diophantine equations where the coefficients and solutions are integers. The techniques used are different and come from number theory. These equations are difficult in general; one often searches just to find the existence or absence of a solution, and, if they exist, to count the number of solutions.

Unknown (2006 film)

Unknown is a 2006 American mystery thriller film directed by Colombian filmmaker Simon Brand and starring Jim Caviezel, Greg Kinnear, Bridget Moynahan, Joe Pantoliano and Barry Pepper about a group of men kidnapped and locked in a factory with no memory of how they arrived there. Piecing together information around them, they realize that some were kidnapped and some were the kidnappers. They decide they must work together to figure out how to get away before the gang that captured them returns.

The film was previewed before a theater audience for the first time in New York City on December 13, 2005.

Plot

In an abandoned warehouse, a handful of men slowly regain consciousness, but they have amnesia and have no idea who they are, where they are, or what has happened to them. All five seem to have been in some sort of serious scuffle; one is tied up on a chair (Joe Pantoliano), another has been handcuffed and shot (Jeremy Sisto), a third has a broken nose (Greg Kinnear), and the other two have their share of scrapes and bruises (Jim Caviezel and Barry Pepper). Everyone is asleep at the start. Caviezel's character wakes up first. He checks to make sure everyone is alive and then decides to walk around and try to find out what is going on. He discovers that all the windows have bars over them and the only door has a mechanized lock. He finds a ringing phone and picks it up. The caller asks what is going on and Caviezel tells the caller that everyone is fine. The Caller tells him he will be back in a few hours. Meanwhile, somewhere else a money drop off is going down. Mr. Coles has been kidnapped.

Jun Kazama

Jun Kazama (風間 準, Kazama Jun) is a fictional character from the Tekken fighting game series, who has made her debut in Tekken 2, her only canonical appearance to date. Following an ambiguous relationship with Kazuya Mishima, she became the mother of Jin Kazama, both of whom are main characters in the series. She is also related to Asuka Kazama and her father.

A nature lover and the mother of Jin Kazama, Jun plays an important role in the story despite of her absence for most of the series. While she was cut from the main series after her debut, Jun has continued to appear in the series' spin-offs, including the Tekken Tag Tournament series, where her alter-ego, Unknown serves as the final boss in all Tag Tournament entries so far. Despite her relatively few appearances, the character has gained a considerable popularity among the fans of the series.

Junior Certificate

The Junior Certificate (Irish: Teastas Sóisearach) is an educational qualification awarded in Ireland by the Department of Education and Skills to students who have successfully completed the junior cycle of secondary education, and achieved a minimum standard in their Junior Certification examinations. These exams, like those for the Leaving Certificate, are supervised by the State Examinations Commission. A "recognised pupil"<ref name"">Definitions, Rules and Programme for Secondary Education, Department of Education, Ireland, 2004</ref> who commences the Junior Cycle must reach at least 12 years of age on 1 January of the school year of admission and must have completed primary education; the examination is normally taken after three years' study in a secondary school. Typically a student takes 9 to 13 subjects – including English, Irish and Mathematics – as part of the Junior Cycle. The examination does not reach the standards for college or university entrance; instead a school leaver in Ireland will typically take the Leaving Certificate Examination two or three years after completion of the Junior Certificate to reach that standard.

The Servant (band)

The Servant was an English alternative band, formed in London in 1998. They are popular in France, Spain, Switzerland as well as other European countries.

Their first introduction to an American audience was in the trailer of the film Sin City with the instrumental version of their song "Cells". This version of "Cells" is not on the Sin City soundtrack, but it can be downloaded via their website ("Cells" was also used in the film The Transporter and Transporter 2, along with their song, "Body"). Since the Sin City trailers, there has been significant U.S. interest in their records and demands for live concerts. The band released their fourth album entitled How To Destroy A Relationship in 2006.

Before achieving commercial success in 2004 with their self-titled album, released by Prolifica Records in the UK and by Recall Group in France, The Servant released two EP's: Mathematics in 1999 and With the Invisible in 2000.

On 26 November 2007, the band announced on their blog at MySpace that they were splitting up "to move on to pastures new".
