The first use of an equals sign, equivalent to 14x + 15 = 71 in modern notation. From The Whetstone of Witte by Robert Recorde of Wales (1557). [1]In mathematics, an equation is a mathematical formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The first true algebra text which is still extant is the work on al-jabr and al-muqabala by Mohammad ibn Musa al-Khwarizmi, written in Baghdad around 825. [53] John J. O'Connor and Edmund F. Robertson wrote in the MacTutor History of Mathematics Archive:
He was "the first who introduced the theory of algebraic calculus". [12] c. 1000 – Abu Mansur al-Baghdadi studied a slight variant of Thābit ibn Qurra's theorem on amicable numbers, and he also made improvements on the decimal system. 1020 – Abu al-Wafa' al-Buzjani gave the formula: sin (α + β) = sin α cos β + sin β cos α.
The first known equation, equivalent to 14x + 15 = 71 in modern notation, from The Whetstone of Witte. (The solution is x = 4) Recorde's introduction of the equals sign in The Whetstone of Witte, "to avoid tedious repetition".
Ancient Egyptian algebra dealt mainly with linear equations while the Babylonians found these equations too elementary, and developed mathematics to a higher level than the Egyptians. [ 7 ] The Rhind Papyrus, also known as the Ahmes Papyrus, is an ancient Egyptian papyrus written c. 1650 BC by Ahmes, who transcribed it from an earlier work that ...
Here thus in the history of equations the first letters of the alphabet became indicatively known as coefficients, while the last letters as unknown terms (an incerti ordinis). In algebraic geometry , again, a similar rule was to be observed: the last letters of the alphabet came to denote the variable or current coordinates .
The first commercial formulas. In 1846, Liebig, an acclaimed German chemist, had described all living tissue, including food, as being composed of different proportions of fats, carbohydrates and ...
Plato (428/427 BC – 348/347 BC) is important in the history of mathematics for inspiring and guiding others. [50] His Platonic Academy, in Athens, became the mathematical center of the world in the 4th century BC, and it was from this school that the leading mathematicians of the day, such as Eudoxus of Cnidus (c. 390 - c. 340 BC), came.
