 What Is So Special About X, Y ,Z In Mathematics? by arinzos(m): 11:26pm On Apr 26, 2020 I have Noticed that in Mathematics, Any problem comes with either Looking for X, Solve for X, Dy/Dx, solve for X, Y and ZWhat Happened to other Alphabets?Is there anything special about X, Y and ZEspecially "X" Re: What Is So Special About X, Y ,Z In Mathematics? by edoairways: 11:31pm On Apr 26, 2020 They are variables it can be any letter anyway 1 Like Re: What Is So Special About X, Y ,Z In Mathematics? by Stephenomozzy(m): 11:36pm On Apr 26, 2020 Other alphabets are used o... X Y Z are used mostly in basic equations... Some crazy more advanced math problems dey exhaust all the consonants sef. Like the Guru above me rightly said, they're just variables often used to indicate an unknown value. It could be symbols self, but the guy who invented the use of letters didn't have an Android phone, if not e for use smileys.

Aside from his father’shelp and a few years at local schools, however,Boole was self-taught in mathematics. When hisfather’s business declined, George had to work tosupport the family. From the age of 16 he taught invillage schools in the West Riding of Yorkshire, andhe opened his own school in Lincoln when he was20. During scant leisure time he read mathematicsjournals in the Lincoln’s Mechanics Institute. Therehe also read Isaac Newton ’s Principia, Pierre-SimonLaplace ’s Traité de mécanique céleste , and Joseph-Louis Lagrange ’s Mécanique analytique and beganto solve advanced problems in algebra.Boole submitted a stream of original papers to thenew Cambridge Mathematical Journal, beginning in1839 with his “Researches on the Theory ofAnalytical Transformations.” These papers were ondifferential equations and the algebraic problem oflinear transformation , emphasizing the concept ofinvariance. In 1844, in an important paper in thePhilosophical Transactions of the Royal Society forwhich he was awarded the Royal Society ’s first goldmedal for mathematics, he discussed how methodsof algebra and calculus might be combined. Boolesoon saw that his algebra could also be applied inlogic.Developing novel ideas on logical method andconfident in the symbolic reasoning he had derivedfrom his mathematical investigations, he publishedin 1847 a pamphlet, “Mathematical Analysis ofLogic,” in which he argued persuasively that logicshould be allied with mathematics, not philosophy .He won the admiration of the English logicianAugustus De Morgan , who published Formal Logicthe same year. On the basis of his publications,Boole in 1849 was appointed professor ofmathematics at Queen’s College , County Cork, eventhough he had no university degree. In 1854 hepublished An Investigation into the Laws of Thought,on Which Are Founded the Mathematical Theories ofLogic and Probabilities , which he regarded as amature statement of his ideas. The next year hemarried Mary Everest, niece of Sir George Everest ,for whom the mountain is named. The Booles hadfive daughters.One of the first Englishmen to write on logic, Boolepointed out the analogy between algebraic symbolsand those that can represent logical forms andsyllogisms, showing how the symbols of quantitycan be separated from those of operation. WithBoole in 1847 and 1854 began the algebra of logic,or what is now called Boolean algebra. Boole’soriginal and remarkable general symbolic methodof logical inference, fully stated in Laws of Thought(1854), enables one, given any propositionsinvolving any number of terms, to draw conclusionsthat are logically contained in the premises . He alsoattempted a general method in probabilities, whichwould make it possible from the given probabilitiesof any system of events to determine theconsequent probability of any other event logicallyconnected with the given events.In 1857 Boole was elected a fellow of the RoyalSociety. The influential Treatise on DifferentialEquations appeared in 1859 and was followed thenext year by its sequel, Treatise on the Calculus ofFinite Differences . Used as textbooks for manyyears, these works embody an elaboration ofBoole’s more important discoveries. Boole’sabstruse reasoning has led to applications of whichhe never dreamed: for example, telephoneswitching and electronic computers use binarydigits and logical elements that rely on Booleanlogic for their design and operation.Boole’s use of symbols and connectives allowed for thesimplification of logical expressions , including such importantalgebraic identities as: ( X or Y) = (Yor X ); not(not X ) = X ; not(X and Y ) = (not X ) or (not Y ); etc.He also developed a novel approach based on a binary system,processing only two objects (“ yes-no ”, “ true-false”, “ on-off ”, “ zero-one”). Therefore, if “true” is represented by 1 and “false” isrepresented by 0, and two propositions are both true, then it ispossible under Boolean algebra for 1 + 1 to equal 1 ( the “+” is analternative representation of the OR operator)Despite the standing he had won in the academic community by thattime, Boole’s revolutionary ideas were largely criticized or justignored, until the American logician Charles Sanders Peirce (amongothers) explained and elaborated on them some years after Boole’sdeath in 1864.Almost seventy years later, Claude Shannon made a majorbreakthrough in realizing that Boole’s work could form the basis ofmechanisms and processes in the real world, and particularly thatelectromechanical relay circuits could be used to solve Booleanalgebra problems. The use of electrical switches to process logic isthe basic concept that underlies all modern electronic digitalcomputers, and so Boole is regarded in hindsight as a founder of thefield of computer science, and his work led to the development ofapplications he could never have imagined.this is he mathematics of relativity where two points meet at X, understanding this law or thought makes one a "0 or 1" unlike bubu who dosent know his bearing or location, booles law transformed mathematics and logic. if nigeria as a county knew the value of Y and Z they would know their X (destination) Re: What Is So Special About X, Y ,Z In Mathematics? by johnkey: 5:05am On Apr 27, 2020 the only maths I know now is \$+£+€+¥
