The main goal of the present work is to provide a general formulation and approach for developing such high-order compact (HOC) scheme for the second-order FIDEs. Then, we consider the extension to problems for the system of equations and apply this strategy to the coupled second-order FIDEs. Comparison studies with previous literature are considered in both cases one and system of integro problems.

It is known that compact difference approximations exist for certain operators that are higher-order than standard schemes. As an example, in [11], the difference coefficients at the five grid points corresponding to the compact patch of three cells surrounding a given node can be selected so the second-order truncation error terms cancel. Therefore utilizing the differential equation, leads to producing alternative lower-derivative expressions equivalent to the higher-order truncation error terms [12].

Which of the following can be expressed as the sum of three consecutive positive integers? A 101 B 202 C 303 D 404 E 505 To determine whether a number can be expressed as the sum of three consecutive positive integers, let's consider how such a sequence behaves. If the three consecutive numbers are \( n \), \( n+1 \), and \( n+2 \) (where \( n \) is a positive integer), their sum would be: \[ n + (n + 1) + (n + 2) = 3n + 3 \] This simplifies to \( 3n + 3 \). Since we are adding three consecutive numbers, the sum must be divisible by 3. Additionally, since we are starting with a positive integer \( n \), the sum must also be odd (as the middle number in our sequence, \( n+1 \), will be even, making the total sum odd). Now let's test each of the provided options: A. 101 - This is an odd number, but we need to check if it's divisible by 3. B. 202 - This is an even number, so it cannot be the sum of three consecutive positive integers. C. 303 - This is an odd number, but we need to check if it's divisible by 3. D. 404 - This is an even number, so it cannot be the sum of three consecutive positive integers. E. 505 - This is an odd number, but we need to check if it's divisible by 3. Now let's check the divisibility by 3 for options A, C, and E. Among the options given, only 303 is divisible by 3. Since 303 is also an odd number, it can be expressed as the sum of three consecutive positive integers. Therefore, the correct answer is: C. 303 If 15 percent of the students in a class are 16 years old or older, what is the least possible number of students in the class?

This work proposes a numerical scheme for the second order and a system Fredholm integro-differential equation by implementing the fourth-order compact finite difference method with Simpson’s quadrature rule. Comparison studies of the higher-order compact and standard methods for such problems are made. The accuracy of the suggested scheme is computed through l^2 and l^∞ norms. The numerical order of convergence R of the scheme is calculated. Numerical experiments are also given and shown that are reliable and yield results compatible with previous studies and analytical solutions.

Math


Several numerical solutions of the integro-differential equations have been studied by compact finite difference methods including[13-15]. Numerous authors have developed numerical methods for integral and integro-differential equations recently, see references [16-23].

Si en la expresión 2^x - 1, x es un número compuesto, entonces se puede escribir como el producto de dos números enteros distintos, digamos a y b, donde a y b son mayores que 1. Por lo tanto, podemos escribir x = a * b. Entonces, la expresión 2^x - 1 se puede reescribir como: 2^x - 1 = 2^(a*b) - 1. Ahora, podemos utilizar la identidad algebraica a^b - 1 = (a-1)(a^(b-1) + a^(b-2)+ ... + a + 1) para factorizar la expresión. Aplicando esta identidad a la expresión 2^x - 1, obtenemos: 2^x - 1 = 2^(a*b) -1 = (2^a)^b - 1. Ahora, podemos ver que esta expresión tiene la forma de una diferencia de cuadrados, es decir, a^2 - b^2 = (a - b)(a + b). De manera similar, podemos factorizar la expresión anterior de la siguiente manera: (2^a)^b - 1 = (2^a - 1)((2^a)^(b-1) + (2^)^(b-2) + ... + (2^a) + 1). Entonces, si x es compuesto, los factores de la expresión 2^x - 1 son (2^a - 1) y ((2^a)^(b-1) + (2^a)^(b-2) + ... + (2^a) + 1), donde a y b son factores enteros distintos de x. Si x es primo, y aun 2^x - 1 sigue siendo primo, entonces sus factores tienen la forma: (2 k1 x + 1)(2 k2 x + 1) = 2^x - 1, de lo que puede observarse: (2 k1 x + 1)(2 k2 x + 1) = 2^x - 1 4 k1 k2 x2 + 2 (k1 + k2) x + 1 = 2^x - 1 4 k1 k2 x2 + 2 (k1 + k2) x = 2^x - 2 2 k1 k2 x2 + (k1 + k2) x = 2^(x - 1) - 1 2 k1 k2 x + (k1 + k2) = (2^(x - 1) - 1) / x (es divisible por el pequeño terema de Fermat) Como x es conocido, 2 k1 k2 x + (k1 + k2) = (2^(x - 1) - 1) / x puede resolverse como una ecuación diofántica 2 a x + b = (2^(x - 1) - 1) / x donde a = k1 k2 y b = k1 + k2, al obtenerse los valores de a y b, pueden obtenerse los de k1 y k2 por la via cuadrática: Establece un algoritmo en javascript para obtener k1 y k2, a partir de x.

THE NUMERAL The numeral denotes an abstract number or the order of thing in succession. In accordance with this distinction the numerals fall into two groups cardinal numerals (cardinals) and ordinal numerals (ordinals). Morphological composition The Cardinals Among the cardinals there are simple, derived, and compound words. The cardinals from one to twelve, hundred, thousand, million are simple words; those from thirteen to nineteen are derived from the corresponding simple ones by means of the suffix -teen; the cardinals denoting tens are derived from the corresponding simple ones by means of the suffix -ty. Note: Mind the difference in the spelling of the stem in three and thirteen (thirty), four and forty, five and fifteen (fifty). The cardinals from twenty-one to twenty-nine, from thirty-one to thirty-nine, etc. and those over hundred are compounds. In cardinals consisting of tens and units the two words are hyphenated: 21 - twenty-one, 35 - thirty-five, 72 - seventy-two, etc. In cardinals including hundreds and thousands the words denoting units and tens are joined to those denoting hundreds, thousands, by means of the conjunction and: 103 - one hundred and three, 225 - two hundred and twenty-five, 3038 - three thousand and thirty-eight, Note: If not part of a composite numeral the words hundred, thousand and million in the singular are always used with the indefinite article; a hundred pages, a thousand ways; in composite numerals both a and one are possible, but one is less common; a (one) hundred and fifty pages. The words for common fractions are also composite. They are formed from cardinals denoting the numerator and substantivized ordinals denoting the denominator. If the numerator is a numeral higher than one, the ordinal in the denominator takes the plural form. The numerator and denominator may be joined by means of a hyphen or without it: 1/3 - one-third (one third), 2/7 - two-sevenths (two sevenths), etc. In mixed numbers the numerals denoting fractions are joined to the numerals denoting integers (whole numbers) by means of the conjunction and: 3 1/5 - three and one-fifth, 20 3/8 - twenty and three-eighths. In decimal fractions the numerals denoting fractions are joined to those denoting whole numbers by means of the words point or decimal: 0.5 - zero point (decimal) five, 2.3 - two point (decimal) three, 0,5 - zero decimal five, 0,005 - zero decimal zero zero five. The ordinals Among the ordinals there are also simple, derivative and compound words. The simple ordinals are first, second and third. The derivative ordinals are derived from the simple and derivative cardinals by means of the suffix -th: four-fourth, ten-tenth, sixteen-sixteenth, twenty-twentieth, etc. Before the suffix -th the final у is replaced by ie: thirty - thirtieth, etc. Mind the difference in the spelling of the stems in the following cardinals and ordinals: five-fifth, nine-ninth. The compound ordinals are formed from composite cardinals. In this case only the last component of the compound numeral has the form of the ordinal: twenty-first, forty-second, sixty-seventh, one hundred and first, etc. Morphological characteristics Numerals do not undergo any morphological changes, that is, they do not have morphological categories. In this they differ from nouns with numerical meaning. Thus the numerals ten (десять), hundred (сто), thousand (тысяча) do not have plural forms: two hundred and fifty, four thousand people, etc., whereas the corresponding homonymous nouns ten (десяток), hundred (сотня), thousand (тысяча) do: to count in tens, hundreds of people, thousands of birds, etc. Patterns of combinability Numerals combine mostly with nouns and function as their attributes, usually as premodifying attributes. If a noun has several premodifying attributes including a cardinal or an ordinal, these come first, as in: three tiny green leaves, seven iron men, the second pale little boy, etc. The only exception is pronoun determiners, which always begin a series of attributes: his second beautiful wife; these four rooms; her three little children; every second day, etc. If both a cardinal and an ordinal refer to one head-noun the ordinal comes first: the first three tall girls, the second two grey dogs, etc. Nouns premodified by ordinals are used with the definite article: The first men in the moon, the third month, etc. When used with the indefinite article, they lose their numerical meaning and acquire that of a pronoun (another, one more), as in: a second man entered, then a third (вошел еще один человек, потом еще). Postmodifying numerals combine with a limited number of nouns. Postmodifying cardinals are combinable with some nouns denoting items of certain sets of things: pages, paragraphs, chapters, parts of books, acts and scenes of plays, lessons in textbooks, apartments and rooms, buses or trams (means of transport), grammatical terms, etc.; Note: In such cases the cardinals have a numbering meaning and thus differ semantically from the ordinals which have an enumerating meaning. Enumeration indicates the order of a thing in a certain succession of things, while numbering indicates a number constantly attached to a thing either in a certain succession or in a certain set of things. Thus, the first room (enumeration) is not necessarily room one (numbering), etc. Compare: the first room I looked into was room five, or the second page that he read was page twenty-three, etc. Postmodifying ordinals occur in combinations with certain proper names, mostly those denoting the members of well-known dynasties: King Henry VIII - King Henry the Eighth, Peter I - Peter the First, etc. Mind the position of the article in such phrases. It is always attached to the numeral. When used as substitutes numerals combine with various verbs: I saw five of them. They took twenty. As head-words modified by other words numerals are combinable with: 1) prepositional phrases: the first of May, one of the men, two of them, etc. 2) pronouns: every three days, all seven, each fifth, etc. 3) adjectives: the best three of them, the last two weeks, etc. 4) particles: just five days ago, only two, only three books, he is nearly sixty, etc. Note: The numeral first may combine with the particle very: the very first of them. When they have the function of subject or predicative the numerals are combinable with link verbs, generally the verb to be: ten were present, the first was my father we are seven, she is the second. Occasionally they are combinable with some other link verbs: two seemed enough, the third appeared to be wounded. Syntactic function Though cardinals and ordinals have mainly similar syntactic functions they differ in certain details. The most characteristic function of both is that of premodifying attribute: two rooms, the third person, etc. In this connection it must be remembered that while the ordinals are used as ordinary attributes, cardinals with the function of an attribute govern the number of the noun they modify: one page, but two (three, etc.) pages. Note 1: Quite unlike Russian, composite cardinals ending in one (twenty-one, thirty-one, two hundred and one, three hundred and twenty-one, etc.) require a plural noun: twenty-one pages, two hundred and one pages. Note 2: In numbering the items of certain sets of things cardinals, not ordinals, are used to modify the nouns denoting these things. The cardinals thus used are always postmodifying. The nouns modified do not take an article: page three, lesson one, room thirty-five, etc. Both cardinals and ordinals may have the functions of subject, object, predicative and adverbial modifier of time: Three of us went home. I saw two of them in the forest. They were seven. She got up at five today. However, in all these cases a noun is always implied, that is, the numeral functions as a substitute for the noun either mentioned in the previous context, or self-evident from the situation. The only case in which the numerals (cardinals) can really have the function of subject, object or predicative is when they are used with their purely abstract force: five is more than three; two plus two is four, etc. Substantivized numerals Numerals can be substantivized, that is, take formal nominal features: the plural suffix -s, an article, and the ability to combine with adjectives and some other modifiers of nouns. When numerals undergo substantivization not only their morphology is changed, but also their meaning. Thus when the numerals hundred, thousand and million are substantivized they acquire the meaning "a great quantity", as in: hundreds of books, thousands of people, millions of insects, etc. Other numerals, both cardinals and ordinals, can also be substantivized. Cardinals are substantivized when they name: 1) school marks 2) sets of persons and things: They came in twos. They followed in fours. Form fours! 3) playing cards: the two of hearts, the five of spades, the seven of diamonds, the ten of clubs, three of trumps. 4) boats for a certain number of rowers: a four, an eight. 5) decades: in the early sixties, in the late fifties, etc. The meaning of substantivized ordinals is less affected by substantivization and remains the same: He was the first to come. She was the fourth to leave. Based on this text, provide detailed answer to the questions: 8. Morphological composition of numerals. 9. Morphological characteristics of numerals. 10. Patterns of combinability of numerals. 11. Syntactic function of numerals.

This work aims to propose a numerical solution of the integro Volterra-differential equation. The proposed method is based on the cubic B-spline method and is linked with the finite element method to solve this type of equation. The term of integral part is carefully handled through Guass rules to approximate the integral of differential equations. These rules allow us to achieve precision in the results. Furthermore, we investigated the coercivity and continuity of suggested problems with a focus on addressing some challenges to deriving the priori error estimate, which leads to proof of convergence analysis. The effectiveness of presented methods is discussed by several examples to demonstrate and illustrate the applicability of the method, and to compare the approximate results and analytical solutions.

In this paper, we introduce numerical methods for solving nonlinear Fredholm integro-differential equations by implementing homotopy perturbation and variational iteration methods. Through extensive computational testing, it was found that the proposed schemes demonstrate accuracy in space. Convergence analysis is performed using contracting mapping. Furthermore, the error bound of an approximate solution generated from the partial sum of the series is explored. Comparison studies between the proposed methods are made. The accuracy of the method is evaluated through numerical examples and shown to outperform existing solutions. Error analysis is conducted using the l∞ and l 2norms, and the efficiency of the approach is assessed. The numerical experiments validate the reliability and compatibility of the results with previous studies and analytical solutions.

Several methods of Fredholm integro-differential equations has been studied by many authors [6, 7, 8, 9]. Alao, at el. [10] employed Adomian decomposition and variational iteration approaches to solve integro-differential equations. Behzadi at el. [2] solved a class of nonlinear Volterra-Fredholm integro-differential equations. Furthermore, many authors have examined several methods for solving integro-differential equations, [11, 12, 13]. A. Daraghmeh, N. Qatanani, and H. Jarar’a worked on three numerical methods to solve linear systems of Fredholm integral equations, namely the Legendre wavelet method, the Taylor series expansion method, 2 Najem A. Mohammad, Mohammad Sh.Hasso and Younis A. Sabawi and the improved block-Pulse functions method [14]. Udaya P. Singh used a new approach to develop a numerical solution to obtain the solution of linear Volterra-type integral equations by obtaining asymptotic approximations to solutions [15]. Tanweer Jalal and Ishfaq Ahmad Malik investigated the infinite system of Hammerstein-type integral equations in two variables[16]. The Homotopy perturbation method (HPM) is a combination of the homotopy method, a fundamental idea in topology, with the traditional perturbation approach. With the help of this coupling, numerous issues that arise in a variety of scientific fields will have an appropriate method to get an approximation or analytical solution. HPM has a few advantages, including the capability to quickly converge the solution series in many cases and the ability to provide good approximations of solutions with a small number of iterations. This approach has been utilized to resolve a variety of problems [17, 18, 19], particularly those involving integral equations. [18, 20, 21, 22, 23, 24]. The aim of this work is to implement homotopy perturbation and veritional iteration methods to find approximate solutions to Eq.(1.1). The goal is to give a convergence condition and error estimation for the solution.
