What are that iteration methods compare different iterative method? What are that iteration methods compare different iterative method? What are the iteration methods? An iterative method is a powerful device of solving and finding the roots of the non linear equations. It is a process that uses successive approximations to obtain more accurate solutions to a linear system at each step. Such a method involves a large number of iterations of arithmetic operations to arrive at a solution for which the computers are very often used in its process to make the task simple and efficient. Iteration means the act of repeating a process usually with the aim of approaching a desired goal or target or result. Each repetition of the process is also called iteration and the results of one iteration are used as the starting point for the next iteration. For example, to solve the quadratic equation we may choose any one of the following iteration methods: a0x^2 +a1x+a2=0 a) Xk+1 = -a2+a0xk^2/a1, k=0,1,2 b) Xk+1= -a2/a0xk+a1,k=0,1,2- Types of iteration methods: Based upon the number of initial approximation values iteration methods can be divided into two categories: Bracketing iteration methods Open end iteration methods Bracketing iteration method: These methods are also known as interpolation methods. Under these methods we start with two initial roots that in bracket, then systematically reduce the width of the bracket until the desired solution is arrived at. There are two popular methods under this category: Bisection method Regular_falsi method Open end iteration method: these methods are known as extrapolation methods. Under these methods we start with one or two initial roots that do not need the bracket the root. These methods are various types: Netwon_raphson method Secant method Mullers method Bisection, regular_falsi and netwon_raphson methods are under root finding algorithm. Root finding algo: A root-finding algorithm is a numerical method, or algorithm, for finding a value x such that f(x) = 0, for a given function f. Such an x is called a root of the function f. Iteration method is obtain the initial approximation to the root is based upon the intermediate value theorem. This theorem is states that: if f(x) is continuous function on some interval[a,b] and f(a).f(b)

french revolution:peasants becoming oppressed. :: essays research papers

By the 18th century the third estate became aware of their oppression through various sources. These sources include the Influence of philosophers and the Echoes of the American war of independence. Goodwin states, the aim of the French philosophers, of the eighteenth century, was to liberate mankind from the fitter of ignorance and from subservience of outmoded practices. D. Richard further illustrated that philosophers such as, Rousseau, Voltaire, Monesquieu and the encyclopedias have contributed to the uprising of the third estate, within the revolution. In fact, Voltaire’s, influence within the revolution was mainly directed towards the corrupt government, ecclesiastical bigotry, censorship and cruel and arbitrary penal systems at the church. D.Richards further stated â€Å"he poured scorn on the pretensions of the church and folly of the government and the credibility of those who are taken by both.† His cry for injustice and brave actions, allowed him to receive tremendous gratitude from the third estate. As a matter a fact, Voltaire was the most influential philosopher within the revolution to challenge. Rousseau also influenced the third estate. Rousseau preached the equality of man, he later attacked justice â€Å"Men though born free are every where in chains†, and even in the government he said. Rousseau according to A. Goodwin claimed that the only legitimate state was one that expressed the â€Å"General will† (the will of the people as a whole) which is inspired by good motives and directed only in the common interest. His contract social (social contract) of 1762 envisaged free men guaranteeing each other natural rights. Historians have concluded that Rousseau, inspired the people emotionally, preparing them to retaliate. Another radical, Montesquieu inspired the third estate within ideas. His aim mainly was to focus on various parts of parlements and it’s unfair implications, towards the third estate. Alongside, the three philosophes mentioned above. Diderot and the encyclopedias also contributed to the influence of the revolution. He, like Voltaire, preached the injustice of the church practices and government. He criticized the heavy burden of taxation upon the third estate. He suggested that the intolerable acts of taxation be abolished with the exception of land tax, which was chiefly paid by the clergy and nobles for Diderot and the encyclopedias the common good was supreme law and government therefore the general happiness of society. Besides the philosophes, the physiocrates played a vital role in the usurpation of the revolution .A. Goodwin also noted that, the physiocrates, led by Rivere, supported freedom of contract, and specifically demanded scientific government to replace the irrationality of privileged.

History of Blackpool †growth and decline Essay

For the majority of the 19th century Blackpool was a small fishing village, which received small numbers of upper class visitors who came due to the supposed healing capabilities of the coast, and it’s fresh air. This changed in 1846 with the creation of a railway line going up to Blackpool, which made travel to the area cheap and affordable for the public. The majority of those who decided to visit Blackpool were factory workers and their families who came from cities like Liverpool and Manchester. Due to air travel being very expensive at the time and only the rich could afford to go abroad. Blackpool became the destination to go to for the working class during their holidays. Blackpool recognised their popularity and over the years constructed three new piers to house new attractions. Three new piers were constructed, named the North, Central and South Piers and were constructed in 1863, 1868 and 1893 respectively. The Winter Gardens, which was effectively an indoor mall, was set up in 1878 and housed an opera house and a theatre. The Blackpool Illuminations, which were put up a year later, and the Blackpool Tower, built in 1894, which housed a Ballroom, Circus Hall and an Aquarium, accompanied this. Due to all these attractions Blackpool became a major tourist destination. In 1930 7 million tourists came to the area and this number increased to 17 million in 1950. Blackpool’s Decline Blackpool began to enter its decline period during the mid 20th century onwards. During this time the disposable income and free time of workers started to increase. This combined with cheaper air flight tickets and package holidays meant that people could go abroad for the first time in their lives. France and Spain were the most popular destinations and over the years started to gain more and more tourists. This took away from the number of people visiting Blackpool. As an attempt to claw back tourists hotels and restaurants in the area started to dramatically decrease their prices with the aim of attracting more tourists. This ended up having the opposite effect. While more tourists did come to the area, they were more downmarket than what Blackpool used to receive. The new crowds attracted by Blackpool were seen as antisocial and unpleasant and removed the family friendly nature associated with Blackpool. The loss of families as potential tourists was a major blow to Blackpool and further added to its decline. Blackpool’s Rejuvenation Recently Blackpool has made attempts to restore its status as a popular tourist destination. Winter Gardens was bought from its private owners and brought back into the public market and a contract with Merlin was made to include the Blackpool Tower with its other hosts of amusement parks. Additionally ? 300 million was spent in improving the state of Blackpool’s infrastructure. While the effort is helping Blackpool it isn’t increasing its status as a tourist destination. Instead of entering Rejuvenation Blackpool has entered a state of slowed decline.

Financial Aid Need or Merit - 890 Words

It is a universal fact that college is not a cheap investment, and acquiring aid to help with the cost can be hard to come by. Due to the recent drop in the economy, it is almost necessary to have a college degree to get a job. The rising cost and necessity of a college education has raised a debate on the eligibility of financial aid and who exactly should obtain the aid. The main focus in the financial aid debate is whether or not aid should be based on merit or need. A simple way to put this is should the student from lower income families receive aid because money is tight, or should students with the best grades get money for working hard and gaining high grade point averages? When both sides are examined,†¦show more content†¦It is easy to expect the government to hand you something but not have to work for it (â€Å"Government Run Financial† 1). In the past few years, need-based aid has become a more popular option explored by colleges due to the recent fall in the economy. Current research shows that the majority of financial aid has begun leaning towards merit-based aid; this has begun to take some money away from those students who financially need it. Also, merit-aid is commonly offered to student with higher family incomes because of their grade point averages and extracurricular records throughout high school (Marcus 1). Without a large sum of money set aside for need-based aid, many students may not be able to attend college. Mark Kantrowitz, the publisher of Fastweb.com and Finaid.com, says â€Å"The most effective use of college grant money is need-based aid. It helps those with the most to gain, and it makes our society stronger in the process.† College may be a difficult goal to accomplish for small income families, but if the students are willing to work hard before college this should not be hard (Should More College 1). It has been proven that low income students are less likely to even apply or attend a four year col lege. In a recent study around 54% of lower income students attended a four year college, while 84% of upper and middle class students were enrolled (â€Å"Should More College† 1).
