An Introduction To Sequences In Mathematics English Language Essay

An Introduction To Sequences In maths English Language EssayThis is an introduction to taking overs. In maths, that is, discrete math hold back learned most(predicate) sequences, which is an ordered list of elements. The sequences is about emplacement of objects, people, tasks, grocery items, books, movies, or poesy, which has an order associated with it.Like a lay, it contains members and the telephone issue of terms. This members is c all in alled elements or terms and the number of terms is in whatever case called the length of the sequences. Sequences having a inbred number. There argon all even rime and odd numbers. This commonly defined fit in to the formula Sn = a, function of n = 1,2,3,a set A= 1,2,3,4 is a sequence. B = 1,1,2,2,3,3, is though the numbers of repeating.There be specific sequences that imbibe their own formulas and methods for fingering the value of terms, such as arithmetic and geometric sequences. List of numbers, finite and infinite, that follow some rules atomic number 18 called sequences.P,Q,R,S is a sequences permitters that differ from R,Q,P,S, as the ordering matters. Sequences tooshie be finite or infinite. For this example is finite sequence. For example of infinite is such as the sequence of all odd positive integers (1,3,5,.). Finite sequences atomic number 18 sometimes cognise as strings or words, and infinite sequences as streams. The empty sequence ( ) is included in most notions of sequence, plainly may be excluded depending on the context.In this subject core sequences, there atomic number 18 covered about indexing, operation on sequences, sequences of integers, subsequences, increasing, decreasing, nonincreasing, nondecreasing, sigma notation, and pi notation. withal that, in this topic also discuss about changing the index and cumber in entireness.BackgroundA sequences was created by Leonardo Pisano Bigollo (1180-1250). Pisano factor from Pisa and Fibonacci which bureau son of Bona cci. He known as by his nickname, Fibonacci. He was earthy in Pisa which is now part in Italy, the city with the famous disposition Tower. He played important role in reviving antiquated methematical skills, as well as making signifi stomacht contributions of his own.He was known for a great interset in math. Beca wont of the Fibonacci Series, He is most known. A serial publication of numbers apostrophizeing reputation reality. For example, 1, 1, 2, 2, 3, 5, 233, 300, 377, The shopping center of the 2 preceding numbers ar from each succeding number.Fibonacci was a member of the Bonacci family and traveled all or so the Mediterranean as a boy. He traveled with his father who held a diplomatic post. To excel in solving a wide flesh of mathematical problems, His keen interest in mathematics and his exposure to other(a) cultures allowed Fibonacci. Fibonacci is probably best known for discovering the Fibonacci sequence.Besides that, A sequences is also was created by Leonardo Fibonacci. He is the Italian mathematician. He also known as Leonardo of Pisa, documented the mathematical sequences often bring in nature in 1202 in his book, Liber Abaci which means book of the abacusIn the sequences, each number is sum of two numbers, such as 1 + 1 = 2, 1 + 2 = 3, 2 + 2 = 4, and so on. That sequence cease be found in the spirals on the skin of a pineapple, sunflowers, seashells, the DNA double ringlet and, yes, pine cones.Sequences is one such technique is a make use of Fibonacci sequences in futures. Fibonacci who was innate in 1170. He found which a elimination reoccurred in nature, as well as a settlement was accompanying from a mathematical judgment of a fibre of numbers a third series is a total of a dual precedent to it.In 2000, A sequence of posters designed at the Issac Newton lend for Mathematical Sciences which were displayed month by month in the trains of London thermionic valve to celebrate world mathematical year 2000. The aim of the posters was to bring maths to life A sequence of posters designed at the Issac Newton make for for Mathematical Sciences. The aim of the posters was to bring maths to life, illustrating the wide applications of modern mathematics in all branches of science includes physical, biological, technological and financial. Each poster gives germane(predicate) mathematical links and information about mathematical.Show more go forth of the researchA sequences is ordered list of elements that normally defined according to this formula, Sn = a function of n = 1,2,3,If S is a sequences Sn n = 1,2,3,,S1 denotes the first elements, S2 denoted the second elements and so on.The indexing set of the sequences,n usually the indexing set is intrinsic number,N or infinite subset of N.In trading operations on sequences, If s = a,b,c,d,e,f is a sequences, then-head of s = a-tail of s = b,c,d,e,f-tail of s = a,b,c,d,e-last s = fFor Concatenation of sequences,If S1 = a,b,c and s2 = d,e.Hence, concatenation of s1 n s2 denoted as = a,b,c,d,eFor this concatenation of sequences, punctuation trade name , mustiness be written mingled with these alphabet.Increasing sequences and decreasing sequences are two important types of sequences. Their relatives are nonincreasing and nondecreasing. Sn Sn+1 is apply when sequences of s is decreasing for all n for which n for which n and n+1 are in the welkin of the sequences. A sequences is nonincreasing if Sn Sn+1 for all n for which n and n+1 are in the domain of the sequences. A sequences is nondecreasing if Sn Sn+1 for all n for which n and n+1 are in the domain of the sequences. utilisation-For increasing, Sn = 2n 1. n= 1, 2, 3,.The first element of s are 1, 3, 5, 7,.For decreasing, Sn = 4-2n, n = 1, 2, 3,The first few elements of s are 2, 0, -2, -4, .For nonincreasing, The sequences 100, 40, 40, 60, 60, 60, 30.For nondecreasing, the sequences of 1, 2, 3, 3, 4, 5, 5The sequences 100, is increasing, decreasing, nonincreasing, nondecreasing since there is no value of i for which both i and i+1 are indexes.A subsequences of a sequences s is a sequences t that consists of certain elements of s retained in the original order they had in s.Example let s = Sn = n n = 1,2,3,1,2,3,4,5,6,7,8,let t = t=2n n = 2,4,6,4, 8, 12,Hence, t is a subsequences of s.Two important operations on numerical sequences are adding and multiplying terms. Sigma notation, sum_i=1100i. is about sum and summation. Summation is the operation of combining a sequence of numbers use addition. Hence, there are become a sum or total.Example sum_i=1ni = fracn2+n2For capital sigma notation, sum_i=mn x_i = x_m + x_m+1 + x_m+2 +dots+ x_n-1 + x_n.Example sum_k=26 k2 = 22+32+42+52+62 = 90Pi is a harvest symbol for product of sequences of terms. This is alsoncaaled multiplication between all natural numbers.Pi notation, prod_i=mn x_i = x_m cdot x_m+1 cdot x_m+2 cdot ,,cdots,, cdot x_n-1 cdot x_n.Example prod_i=26 left(1 + 1over iright) = left(1 + 1over 2rig ht) cdot left(1 + 1over 3right) cdot left(1 + 1over 4right) cdot left(1 + 1over 5right) cdot left(1 + 1over 6right) = 7over 2.Changing the index and limits in a sum.The formula to change the index and limit to the sum is,_(1=0)n--ir-n-1Limit of SequenceThe notation of limit of a sequence is rattling natural. The fundamental concept of which the whole of analysis ultimately rests is that of the limit of the sequence. By considering some examples can make the position clear.Consider the sequenceIn this sequence, no number is goose egg. But we can watch that the finisher to zero the number of, the larger the number of n is. This state of relation can express by saying that as the number of tends to 0, the n increases, or that the sequence can converges to 0, or that they possess the limit to 0. The points crowd closer n closer to the point 0 as n increases this means that the numbers are represented as points on a line. This perspective is similar in the case of the sequenceHere, t oo, as n increases, the numbers tends to 0 the only difference is that the numbers are sometimes less(prenominal) than and sometimes greater the limit 0 as we say, they oscillate about the limit. The convergence of the sequence to 0 is usually expressed by the equating or occasionally by the abbreviation.We consider the sequence where the intrinsical index n takes all the value 1, 2, 3 . . We can get out at once that as n increases, the number will approach closer and closer to the number 1 if we write, in the sense that if we mark off any interval about the point 1 all the numbers following a certain must fall in that interval. We writeThe sequence behaves in a similar focal point. This sequence also tends to a limit as n increases, to the limit 1, in symbols, . We see this most readily if we write . Here, we need to show that as n increases the number tends to 0.For all value of n greater than 2 we have and. Hence, for the remainder we have , from which at once that tend to 0 a s n increases. It is also gives an estimate of the amount by which the number (for can differ maximum from the limit 1 this certainly cant get over . The example only considered illustrates the fact to naturally expect that for large values of n the terms with the highest indices in the numerator and denominator of the fraction for predominate and that they determine the limit.Applications1)Fibonacci numberNowadays or in era science of technology, We will find a Fibonacci number using C++ programming. The following sequences are considered1, 1, 2, 3, 5, 8, 13, 21, 34,.Two numbers of the sequence, a_1 and a_2 , the nth number a_n, n =3.a_n = a_(n-1) + a_(n-2).Thus, a_3 = a_1 + a_2 = 1 + 1 = 2,a_4 = a_2 + a_3, and so on. such a sequence is called a Fibonacci sequence. In the preceding sequence, a_2 = 1, and a_1 = 1, However any first two numbers, using this process. Nth number a_n, n = 3 of the sequnces can be determined. The number has been determined this federal agency is called the nth Fibonacci number. a_2 = 6 and a_1 = 3. Then, a_3 = a_2 + a_1 = 6 + 3 = 9,a_4 = a_3 + a_2 = 9 + 16 = 15.2) Draft snakeThis spunky is most famous a long time ago. But now, a new generation still playing this game at desolate time. This game is closely with sequences which is about the numbers or all natural number but in this game, only positive number that have in this checker. However, it still in a sequences. Firstly, a player must play a dice to get a number so that he or she can move one place to some other place to get a winner. These place to pleace is refer to the number. Each number that get from a dice will moves our position until he or she become a winner.ConclusionAs we know, a sequences is about a series of numbers. A series of numbers in sequences, which is all natural number includes positive and negative integers, could be a finite sequence from some data source or an infinite sequence from a discrete dynamical system. All of the schoolchilds, which is the students from the programming course learn about this topic in discrete mathematic as a minor theatre in their course. Majoriti of the students said that this topic very interesting to learn and aristocratical to sexual conquest to get a highest marks in examination, test and others.Although this topic was considered very interesting to learn and easy to get a highest marks, but in this topis is also have a part that unwieldy to score and bored to learn. A difficult part was identified is the formula that used in this sequences. For example, one of the subtopic in a sequences is when to changing the index and limits in a sum, _(1=0)n--irn-1-. This formula is difficult to remembered among of the students. It is not only difficult to remembered, but a student is also difficult to remembered a way to calculate this problem where a question want a student change the index and limits in a sum.So, to cultivate these problem, another way must be created so that a student can solve th ese problem easier. May be a formula is fixed means it cannot be changed. Nowadays, a lot of ways was created by among of students to solve these problem. So another ideas must found themselves so that it easier to remembered.As a ending here, the subtopics in a sequences has interesting to learn and not interesting to learn. Besides that, it has easy to remembered and not easy to remembered. Here, does not all of topic are easy. This condition mest be identified so that a problem can be solved immediately and corretly among the students.
