Definition The 1st degree polynomial function, or related function, is any function f from IR to IR given by a law of the form f (x) = ax + b, where a and b are given real numbers and a 0. In function f (x) = ax + b, the number a is called the coefficient of x, and the number b is called the constant term. Here are some examples of 1st degree polynomial functions: f (x) = 5 x - 3, where a = 5 and b = - 3 f (x) = -2 x - 7, where a = -2 and b = - 7 f ( x) = 11 x, where a = 11 and b = 0 Graph The graph of a polynomial function of the first degree, y = ax + b, with a 0, is an oblique line to the axes O x and O y.
We start with the following equality: 0 = 0 We can write equality as follows: 3-3 = 4-4 We highlight 3 and 4: 3 (1-1) = 4 (1-1) Cut the common terms in parentheses and we come to equality: 3 = 4 Obviously this demonstration has an error because we all know that 3 is not equal to 4 (or does anyone have any questions?
Augustus de Morgan was born in 1806 in India and died in 1871. He was an Indian mathematician and teacher based in England, one of the founders of BAAS. He studied at Trinity College, graduating fourth, not joining Cambridge and Oxford for refusing to take the religious exam. But he went on to teach mathematics at the age of 22 at the newly founded University of London, which would later be called University College.
Niels Henrik Abel was born on August 5, 1802 in Finnoy, Norway, and died on April 16, 1829 in Froland, Norway. He proved the impossibility of algebraically solving the general fifth degree equation. Abel's life was dominated by poverty. After the death of his father, who was a Protestant minister in 1820, Abel had a responsibility to support his mother and family.
Karen Daltoé Matheus Silveira Concern about obtaining a consistent, above all human, vocational training led us to attend the Special Education discipline that would provide us with the initial basic knowledge so that we could meet students with special educational needs.
Let's check: We start with the following equality, which is true: 16-36 = 25-45 We add (81/4) on both sides, which does not change equality: 16-36 + (81/4) = 25-45 + (81/4) This can be written as follows: (perfect square trinomial) (4- (9/2)) 2 = (5- (9/2)) 2 Taking the square root on both sides we have: 4- (9/2) = 5- (9/2) Adding (9/2) on both sides of equality we get: 4 = 5 As 4 = 2 + 2 we come to the following conclusion: 2 + 2 = 5 Obviously this demonstration has an error because we all know that 2 + 2 is not equal to 5 (or does anyone have any questions?
Amalie Emmy Noether, Germanic mathematics, was born on March 23, 1882 in Erlange, Bavaria (Germany), and died on April 14, 1935. She was the eldest daughter of a Jewish family of four. He completed his doctorate with a dissertation on algebraic invariants and gained notoriety for his work in abstract algebra.
Adriano Beluco Abstract This article aims to highlight the potentialities of the exploration of factors of the student's daily life in the classroom. From the mass media, more specifically the cartoons, it is possible to use the mathematical argument for the formation of critical consciousness, prioritizing not only the construction of knowledge of students, but also the formation of personality.
Abstract This article seeks to reflect on the methodological application used in teaching the Bháskara Formula in the 9th grade elementary school math classes, as well as to highlight aspects that make it possible to apply it. .
Aristarchus (320 BC - 250 BC) was born in Samos, Greece. Perhaps as an astronomer, he was not as prominent as he deserved in the history of mathematics until the present day. For example, Thomas Heath began the second volume of his history of Greek mathematicians with the following words: The History of Mathematicians has as a rule to pay little attention to Aristarchus of Samos.
Georg Ferdinand Ludwig Philipp Singer was born on March 3, 1845 in St.Petesburg, Russia, and died on January 6, 1918 in Halle, Germany. He founded set theory and introduced the concept of infinite numbers with his discovery of cardinal numbers. He also advanced the study of trigonometric series.
Joost Bürgi was born on February 28, 1522 in Lichtensteig, Switzerland, and died on January 31, 1632 in Kassel (now Germany). He was the most skillful, and most famous man who worked with watches in his day. He also made important scientific instruments, notably for Hesse-Kassel Wilhelm der Weise's Landgraf, who combined governing his state with being a first-class astronomer.
Arthur Cayley was born August 16, 1821, and died January 26, 1895. He was an English mathematician who made a major contribution to the advancement of pure mathematics. Graduating (1842) at Trinity College, Cambridge, he later entered law and was admitted (1849) to the London Bar. Cayley developed the theory of algebraic invariance, and his development of non-dimensional geometry was applied in physics for the study of CONTINUOUS SPACE-TIME QUANTITY.
Elena Lucrezia Cornaro Piscopia was born in a poor family on June 5, 1646 in Venice, Italy. He died July 26, 1684. His father, Giovanni Baptista Cornaro, was the San Marco Prosecutor. His mother, Zanetta Giovanna Boni, was not a privileged class member before their marriage. Elena's father spent his life establishing the name of Cornaro, a name that should be remembered forever because of his eldest daughter's intellect.
Charles Babbage was born on December 26, 1791 in London, the son of a banker. His family provided him with a wealthy life from the start. He fell in love with mathematics early on but was unhappy with teaching at Cambridge, studying for himself the works of Newton, Leibniz, and Euler.
Farkas Bolyai (1775-1856) was born in Bolya, near Nagyenyed (Hungary) on February 9, 1775. His family had a long historical past; some members were remembered as fighters against the Turks, other active participants in Transylvanian politics; however, they became impoverished. And so his father, Gáspár Bolyai, owned only a small estate in Bolya, and his mother, Kristina Pávai Vajua, had also inherited a small farm in Marosvásárhely.
ÉVarist Galois was born near Paris, in the village of Bourg la-Reine, where his father was mayor. At age 12 he showed little interest in Latin, Greek and Algebra but Legendre's geometry fascinated him. At the age of 16, judging himself to be fit, he sought entry into the Polytechnic School but was refused for lack of preparation and this marked his first failure.
Pierre de Fermat was born on August 17, 1601 in Beaumont-de-Lomages, France, and died on January 12, 1665 in Castres, France. He was a lawyer and government official in Toulouse for most of his life. Mathematics was his hobby. In 1636 Fermat proposed a system of analytic geometry similar to that Descartes would propose a year later.
Marguerite Lehr was born on October 22, 1898 in Baltimore, Marylande and died on December 14, 1987. Marguerite studied at a Baltimore public school. The only subject that had difficulty at school was in algebra, however, after scoring in the first trimester as she herself said, "I could have been docile and learned the rules, so I spent the second trimester with 95.
Carl Gustav Jakob Jacobi (1804 - 1851) was born in Germany. His father was a prosperous banker, never missing anything. He obtained a good education at the University of Berlin, focusing on Philosophy and Mathematics to which he devoted himself entirely. He was a born teacher and liked to convey his ideas.
The French physicist Joseph Louis Lagrange was born on January 25, 1736 and died on April 10, 1813. He was one of the most important mathematical and physical scientists of the late 18th century. He invented and brought about the calculus of variations and then applied them. the new discipline for CELESTIAL MECHANICS, especially for finding improved solutions to the THREE-BODY PROBLEM.
