  1. The Mandelbrot set is a set of points in a complex plane, c, of the orbit, which is how the function operates under the iteration of zn+1 = zn2 + c around 0.

    This can repeated by letting c be x for the next iteration in the original equation, and this will yield c2 + c. You can continue repeating putting the previous answer in for x into the equation and the result will be (c2 + c) 2 + c. Doing this continuously will create a list of complex numbers and if these complex numbers are increasing in size and thus further away from the origin then 'c' is not in the Mandelbrot Set.

  2. Bridges of Knigsberg & Eulerian circuits

    The way Euler solved it was by thinking of the river and bridges in terms of graph theory. This was achieved by removing anything unnecessary to the problem and so therefore ended up drawing a picture primarily consisting of points that represented the islands and separate lines showing the bridges that connected the islands.2 Figure 2 shows the picture of what Eular might have drawn up. Fig. 2 As you can see the problem now looks much simpler and one could attempt to solve by just using a pencil and going around the lines looking for a solution but to find a systematic approach to is incredibly tedious laborious.

  3. Maths Economics

    equals an economy's total output (equivalent to real income, Y, or GDP). To keep the link with the historical meaning, the IS curve can be said to represent the equilibria where total private investment equals total saving, where the latter equals consumer saving plus government saving (the budget surplus) plus foreign saving (the trade surplus). In equilibrium, all spending is desired or planned; there is no unplanned inventory accumulation.[6] The level of real GDP (Y) is determined along this line for each interest rate. Thus the IS curve is a locus of points of equilibrium in the "real" (non-financial)

    s(8) = 4 s(10) = 0 s(345) = 5 s(27,560) = 0 s(738,954,683,012) = 4 Using mental arithmetic I can calculate 82 and 102 quite easily. However calculating 738,954,683,0122 is very challenging to say the least. So how can I be confident that my answers are correct? Using the Arabic-Hindu numeral system of hundreds, tens, units etc. and the following simple theory of multiplication I am confident of my answers being correct. Using a three digit number and each number is represented by letters. Let the first three digits of the first number be 'a' (hundreds digit)

  5. Essay on Professor V Lakshmikantham - A great mathematician

    He published a book "Theory of Fuzzy Differential Equations and Inclusions" as an author. This was when he was a Professor and the Head of Applied Mathematics at the Florida Institute of Technology in Melbourne. This book was about complicated differential equations were applied to real-world problems in subjects like engineering, computer science, and social science. His proofs and solutions made quick and recent developments. Also these equations were presented in a detail way and includes the basics for "fuzzy set theory".

    A1 ? A2 ? ... ? An = S (assembling all the pieces yields the original sphere S) There exist T1, T2, ... Tn, where each Ti represents some finite sequence of rotations and translations, such that if we apply each Ti to each Ai (let's call the result Ai'), then: A1' ? A2' ? ... ? Am' = S (a subset of the original pieces forms S) Am+1' ? Am+2' ? ... An = S' (the remaining pieces forms a copy of S) where m is some number between 1 and n, and S' is S translated by some finite amount so that S and S' are disjoint.

  7. Development of Calculus

    Newton and Leibniz clearly owed much to their immediate predecessors, but their mutual influence during the crucial periods when they were making their own original inventions was minimal.1 A controversy arose from the respective claims made by Newton and Leibniz and their supporters to priority in the 'invention' of the calculus. This controversy was extremely bitter and its repercussions were not without influence on the history of mathematics in the 18th century alienating British mathematics from the developments in the rest of Europe.

    It was based on powers of ten from one to one million. The number one was illustrated by a short length of rope. The number ten was shown as a horseshoe of a longer piece of rope. One hundred, a coil of rope. Rope was used as a hieroglyphic in different shapes and lengths to signify the key role of the "rope stretchers" of ancient Egypt.2 The hieroglyphic for one thousand was a lotus flower, a finger represented ten thousand, one hundred thousand was pictured as a tadpole/frog, and anything as large one million or more was illustrated by a man with raised arms.

    The output of a search algorithm is either a failure or a solution. The efficiency of a search algorithm can be evaluated in four ways [1] * Completeness: Is the algorithm guaranteed to find a solution when it exists? * Optimality: Does the strategy find the optimal solution? * Time Complexity: The time taken to find the solution * Space Complexity: The memory needed to perform the search 1.1 Background Search algorithms have been used extensively to solve various problems like the Queens problem, the dining philosophers problem etc.

  11. 'The debates between Keynes and the "classical" economists are only of interest to economic historians; they are of no relevance to modern policymakers.'

    i The above quote shows how Adam Smith described this by using his theory of the 'invisible hand' to back it up. The classical model of the economy suggests that all markets are always at equilibrium. The labor market failing to reach equilibrium level cannot exist in the classical model because of the competitive exchange equilibrium. This way quantities and prices can adjust accordingly. The classical model is for a closed economy and the variable are employment, real and nominal wages, prices levels, interest rates and real output.

    I also plan to find the relationships / sequence between any two of these characteristics of the line(s). I will accomplish this by using the following formula: A+B (n+1) +0.5(n-1) (n-2) C. A = 1st term of the sequence. B = the difference between the first two terms. C = the 2nd difference (the difference of the 1st difference). Thirdly I will put all my findings onto to a table consisting of total regions, closed regions, open regions, crossover points and all of the formulas. Lastly I will try to summarize all my findings by writing up a conclusion and evaluation.

    Unfortunately biological pest control methods alone are rarely sufficient. Research suggest that an integrated approach, using pesticides, biological pest control and other techniques may be the most affective. In general terms, biological pest control is the use of a specially chosen living organism to control a particular pest. This chosen organism might be a naturally occurring parasites, predator, or disease that will attack a harmful insect.

  16. This paper intends to examine the words starting with <sn> given in the Oxford English Dictionary, and if possible categorise them, according to shared meaning. It will examine briefly the academic background to Sound symbolism

    Clustering is concerned with words which share sounds that have meaning at vowel and consonant level; Magnus (1997) refers to this as the Semantic Association. An example of Semantic Association given by Magnus is that if in any language the given word for house begins with an <h> or a <t> or even an <i> then by the process of clustering it would be expected that a disproportionately large number of words concerning housing would also being with that letter, <h> or <t> of <i>. So therefore in English we have house with the other house words including hut, home, hacienda, and hovel.

    manifold * Mass flow rate * Compression stroke * Torque generation and acceleration Additional components can be added to the model to gain greater accuracy in the simulation. Throttle The simulation on the throttle body is based on the control input of the angle of the throttle plate. The rate in which the model induces air into the intake manifold can be expressed as the outcome of two functions. One is the function of the throttle plate angle and the other is an atmospheric function of the manifold pressure.

  20. Edgar Allan Poe's The Raven is 108 lines long, and is written introchaic octameter, therefore having 16 syllables per line, less thelast line of each stanza, which is trochaic, but having only seven

    Poe uses alliteration in writing, "doubting, dreaming dreams no mortal ever dared to dream before." Assonance, consonance, and alliteration pervade The Raven, creating a melodic and rhythmical facet of the poem. The second, fourth, fifth, and final line of every stanza end with the "ore" sound, with such words as implore, nevermore, Lenore, lore, and yore. Every stanza contains 6 lines, there are no perturbations from this pattern. The poem is nearly acatalectic- a few of the deviate from the octameter, such as line 62, which contains a mere 15 syllables. The atmosphere created by Poe especially appeals to the readers senses- the narrator apprises the reader that it is during the month of December,

Encourage them to keep moving, move into space and to change direction. (8 minutes) Ask the children to come up with three or four ways of travelling using a combination of hands and feet remembering to think about direction. Using mats they should practice these three or four travelling movements. They should also think of a starting and finishing position.

    = cos x. So from this, we can also state that that is the same thing as g(x1) = cos x1. Hence, if we make the substitution, it would result to x2= cos x1, where we can further substitute the x1 to 1, making the whole equation x2= cos 1. This would then be the first iteration. Subsequently, this entire substitution process would be repeated another four times, each time using the previous answer as a substitute. The calculations below will provide a better understanding of the concept. 1st iteration, n = 1 2nd iteration, n = 2 3rd iteration, n = 3 x1+1 = g(x1)

"Archimedes will be remembered when Aeschylus is forgotten, because languages die and mathematical ideas do not."

- G. H. Hardy

Have you ever wondered how we can be certain that there are infinitely many prime numbers? If you have, you should consider studying mathematics. Mathematicians will tell you, sometimes arrogantly, that maths is the most challenging subject in the world. They may have a point: it's hard to think creatively and rigorously at the same time, and for a university degree in mathematics, that's exactly what you have to do. That and a lot of problem sets.

But if you think that mathematics means no writing, youre mistaken. The only way to communicate results is through language: proofs and maths papers will require writing, and you'll probably be assigned a final year project as well. Luckily, Marked by Teachers can help. Study our marked papers, and it will only be a matter of time before writing well-structured arguments is second nature to you.

A mathematics degree will change the way you think forever. When you graduate, you'll be set to pursue a whole slew of careers including research, banking,economics, computer science, information technology, and statistics.
