The TI-59 is an early programmable calculator, that was manufactured by Texas Instruments from 1977. It is the successor to the TI SR-52, quadrupling the number of "program steps" of storage, and adding "ROM Program Modules" (an insertable ROM chip, capable of holding 5000 program steps).
501 is the sum of the first eighteen primes. [1] There are 501 degree-8 polynomials with integer coefficients, all of whose roots are in the unit disk. [ 2 ] There are 501 ways of partitioning the digits from 0 to 9 into two sets, each of which contains at least two digits, [ 3 ] and 501 ways of partitioning a set of five elements into any ...
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
Desmos was founded by Eli Luberoff, a math and physics double major from Yale University, [3] and was launched as a startup at TechCrunch's Disrupt New York conference in 2011. [4] As of September 2012 [update] , it had received around 1 million US dollars of funding from Kapor Capital , Learn Capital, Kindler Capital, Elm Street Ventures and ...
The first American-made pocket-sized calculator, the Bowmar 901B (popularly termed The Bowmar Brain), measuring 5.2 by 3.0 by 1.5 inches (132 mm × 76 mm × 38 mm), came out in the Autumn of 1971, with four functions and an eight-digit red LED display, for US$240, while in August 1972 the four-function Sinclair Executive became the first ...
Floating-point numbers are only supported for base 10. However, it is still far more powerful (though also much more expensive) than contemporary competitors such as the non-programmable computer math calculator Casio CM-100 [ 4 ] [ 5 ] or the TI Programmer [ de ] , [ 6 ] [ 7 ] LCD Programmer [ 8 ] [ 9 ] [ 10 ] or Programmer II .
Introduced by HP for students, the HP 10s (F2214A) is a scientific calculator with more than 240 built-in functions, with 2 lines x 10 digits LCD. It is permitted to use on SAT and ACT tests. [3] It has a standard scientific layout and function set that very closely correlates with the Casio fx-85MS, allowing for calculations to be done in a ...
