), and it is in the Mechanics of Heron (first century A.D.) of Alexandria.It was also the first corollary in Isaac Newton’s (1642--1727) Principia Mathematica (1687). In symbols, if a, b, and c are the lengths of the sides: Area = s(s - a)(s - b)(s - c) where s is half the perimeter, or (a + b + Heron's formula is a special case of Brahmagupta's formula for the area of a cyclic quadrilateral. All that is known about the life of Liu Hui is that he lived in the northern Wei kingdom (see Three Kingdoms) during the 3rd century ce. As having an absolute purpose to describe and document aspects of the observed natural world and universe. Try a web search. They were able to draw on and fuse together the mathematical developments of both Greece and India. The study of mathematics as a subject begins in the 6th century BC when the Pythagoreans originate the word mathematics. You’ll find something like this: Heron's formula is named after Hero of Alexendria, a Greek Engineer and Mathematician in 10 - 70 AD. His fame rests on the commentary he completed in 263 on Jiuzhang suanshu (The Nine Chapters on the Mathematical Art)—a The parallelogram law for the addition of vectors is so intuitive that its origin is unknown. History of Vectors. Following on from early movements towards the use of symbolic expressions in mathematics by Diophantus, Al-Khwarizmi and François Viète, “La Géométrie” introduced what has become known as the standard algebraic notation, using lowercase a, b and c for known quantities and x, y … Heron's formula and Brahmagupta's formula are both special cases of Bretschneider's formula for the area of a quadrilateral. Liu Hui, Chinese mathematician. Hero(or Heron) of Alexandria was a Greek mathematician and engineer whose major contributions to mathematics were Hero's formulaand the first approximation in Greece of a number's square root. This nicely fit their objective for accuracy. That mathematics itself could be studied, as pure mathematics, to reveal or uncover knowledge by logic and reason was … Famous Mathematicians Mathematics is a field that many people shy away from, but there are some who had a passion for numbers and making discoveries regarding equations, measurements, and other numerical solutions in history. It is established based on the fact that most of his work that survived through the ages in writing is in the form of lecture notes on mathematics, mechanics and physics. • Heron ’s contributions to mathematics include: • Hero described a method of iterativ ely computing the square root. He is best known for his contributions to geometry. Mathematics is a field that many people shy away from, but there are some who had a passion for numbers and making discoveries regarding equations, measurements, and other numerical solutions in history. They looked for ways to understand the world as it …
