Version 3 of Lotus 1-2-3, fully converted from its original macro assembler to the more portable C language, was delayed by more than a year as the totally new 1-2-3 had to be made portable across platforms and fully compatible with existing macro sets and file formats. The inability to fit the larger code size of compiled C into lower-powered ...
[2] Before 50 BC - Babylonian cuneiform tablets show use of the Trapezoid rule to calculate of the position of Jupiter. [3] 3rd century - Liu Hui rediscovers the method of exhaustion in order to find the area of a circle. 4th century - The Pappus's centroid theorem,
The new introduction defines "elementary propositions" as atomic and molecular positions together. It then replaces all the primitive propositions 1.2 to 1.72 with a single primitive proposition framed in terms of the stroke: "If p, q, r are elementary propositions, given p and p|(q|r), we can infer r. This is a primitive proposition."
Calculated Industries' first entry into the calculator business came in the later 1970s with The Loan Arranger. [1] It was one of the first Real Estate calculators to simplify the process of calculating a loan payment, breaking away from the traditional financial key labeling of “I”, “PV”, “FV” to more clearly labeled function keys.
SuperCalc was CA Technologies' first personal computer product. [2] The MS-DOS versions were more popular with many users than the market-leading Lotus 1-2-3, because it was distributed without copy protection, [3] as well as being priced lower. By the release of version 3 in March 1987, a million users were claimed. [4]
1) An unknown is named and an equation is set up 2) An equation is simplified to a standard form( al-jabr and al-muqābala in arabic) 3) Simplified equation is solved [40] Diophantus does not give a classification of equations in six types like Al-Khwarizmi in extant parts of Arithmetica.
260 BC – Greece, Archimedes proved that the value of π lies between 3 + 1/7 (approx. 3.1429) and 3 + 10/71 (approx. 3.1408), that the area of a circle was equal to π multiplied by the square of the radius of the circle and that the area enclosed by a parabola and a straight line is 4/3 multiplied by the area of a triangle with equal base ...
The treatise also provides values of π, [107] which Chinese mathematicians originally approximated as 3 until Liu Xin (d. 23 AD) provided a figure of 3.1457 and subsequently Zhang Heng (78–139) approximated pi as 3.1724, [114] as well as 3.162 by taking the square root of 10.
