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 Z What Happened to other Alphabets? Is there anything special about X, Y and Z Especially "X" |

They are variables it can be any letter anyway 1 Like |

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. (joking) 1 Like |

arinzos:Yes X and Y are special because they can't be confused as numbers Let's imagine this. q,a and p can be seen as 9 b, h and g can be seen as 6 c, m,n and o can be seen as zero f and t can be seen as 7 I, l and j can be seen as 1 S can be seen as 8 Z can be seen as 2 1 Like 1 Share |

George Boole , (born November 2, 1815, Lincoln, Lincolnshire , England—died December 8, 1864, Ballintemple, County Cork , Ireland), English mathematician who helped establish modern symbolic logic and whose algebra of logic, now called Boolean algebra, is basic to the design of digital computer circuits. Boole was given his first lessons in mathematics by his father, a tradesman, who also taught him to make optical instruments. Aside from his father’s help and a few years at local schools, however, Boole was self-taught in mathematics. When his father’s business declined, George had to work to support the family. From the age of 16 he taught in village schools in the West Riding of Yorkshire, and he opened his own school in Lincoln when he was 20. During scant leisure time he read mathematics journals in the Lincoln’s Mechanics Institute. There he also read Isaac Newton ’s Principia, Pierre-Simon Laplace ’s Traité de mécanique céleste , and Joseph- Louis Lagrange ’s Mécanique analytique and began to solve advanced problems in algebra. Boole submitted a stream of original papers to the new Cambridge Mathematical Journal, beginning in 1839 with his “Researches on the Theory of Analytical Transformations.” These papers were on differential equations and the algebraic problem of linear transformation , emphasizing the concept of invariance. In 1844, in an important paper in the Philosophical Transactions of the Royal Society for which he was awarded the Royal Society ’s first gold medal for mathematics, he discussed how methods of algebra and calculus might be combined. Boole soon saw that his algebra could also be applied in logic. Developing novel ideas on logical method and confident in the symbolic reasoning he had derived from his mathematical investigations, he published in 1847 a pamphlet, “Mathematical Analysis of Logic,” in which he argued persuasively that logic should be allied with mathematics, not philosophy . He won the admiration of the English logician Augustus De Morgan , who published Formal Logic the same year. On the basis of his publications, Boole in 1849 was appointed professor of mathematics at Queen’s College , County Cork, even though he had no university degree. In 1854 he published An Investigation into the Laws of Thought, on Which Are Founded the Mathematical Theories of Logic and Probabilities , which he regarded as a mature statement of his ideas. The next year he married Mary Everest, niece of Sir George Everest , for whom the mountain is named. The Booles had five daughters. One of the first Englishmen to write on logic, Boole pointed out the analogy between algebraic symbols and those that can represent logical forms and syllogisms, showing how the symbols of quantity can be separated from those of operation. With Boole in 1847 and 1854 began the algebra of logic, or what is now called Boolean algebra. Boole’s original and remarkable general symbolic method of logical inference, fully stated in Laws of Thought (1854), enables one, given any propositions involving any number of terms, to draw conclusions that are logically contained in the premises . He also attempted a general method in probabilities, which would make it possible from the given probabilities of any system of events to determine the consequent probability of any other event logically connected with the given events. In 1857 Boole was elected a fellow of the Royal Society. The influential Treatise on Differential Equations appeared in 1859 and was followed the next year by its sequel, Treatise on the Calculus of Finite Differences . Used as textbooks for many years, these works embody an elaboration of Boole’s more important discoveries. Boole’s abstruse reasoning has led to applications of which he never dreamed: for example, telephone switching and electronic computers use binary digits and logical elements that rely on Boolean logic for their design and operation. Boole’s use of symbols and connectives allowed for the simplification of logical expressions , including such important algebraic 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” is represented by 0, and two propositions are both true, then it is possible under Boolean algebra for 1 + 1 to equal 1 ( the “+” is an alternative representation of the OR operator) Despite the standing he had won in the academic community by that time, Boole’s revolutionary ideas were largely criticized or just ignored, until the American logician Charles Sanders Peirce (among others) explained and elaborated on them some years after Boole’s death in 1864. Almost seventy years later, Claude Shannon made a major breakthrough in realizing that Boole’s work could form the basis of mechanisms and processes in the real world, and particularly that electromechanical relay circuits could be used to solve Boolean algebra problems. The use of electrical switches to process logic is the basic concept that underlies all modern electronic digital computers, and so Boole is regarded in hindsight as a founder of the field of computer science, and his work led to the development of applications 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) |
