The original TI-30. The TI-30 is a scientific calculator manufactured by Texas Instruments, the first model of which was introduced in 1976.While the original TI-30 was discontinued in 1983 after several design revisions, TI maintains the TI-30 designation as a branding for its low and mid-range scientific calculators.
The Arithmometer, invented in 1820 as a four-operation mechanical calculator, was released to production in 1851 as an adding machine and became the first commercially successful unit; forty years later, by 1890, about 2,500 arithmometers had been sold [16] plus a few hundreds more from two arithmometer clone makers (Burkhardt, Germany, 1878 ...
Krippendorff's alpha coefficient, [1] named after academic Klaus Krippendorff, is a statistical measure of the agreement achieved when coding a set of units of analysis.. Since the 1970s, alpha has been used in content analysis where textual units are categorized by trained readers, in counseling and survey research where experts code open-ended interview data into analyzable terms, in ...
The number e is a mathematical constant approximately equal to 2.71828 that is the base of the natural logarithm and exponential function.It is sometimes called Euler's number, after the Swiss mathematician Leonhard Euler, though this can invite confusion with Euler numbers, or with Euler's constant, a different constant typically denoted .
Each fraction / (in lowest terms) has a circle tangent to the line at the point (/,) with curvature . Three of these curvatures, together with the zero curvature of the axis, meet the conditions of Descartes' theorem whenever the denominators of two of the corresponding fractions sum to the denominator of the third.
No use coming into RAND before 10:00 am when JOSS arrives, in fact noon or after 5:00 pm is a better time, JOSS is less busy. When JOSS starts typing answers, the titillating pleasure is equaled only by the ensuing anguish when JOSS breaks off into jibberish or goes away commending your code to oblivion. We can hardly live with JOSS, but we can ...
Metric equivalents are based upon one of two nearly equivalent systems. In the standard system the conversion is that 1 gallon = 231 cubic inches and 1 inch = 2.54 cm, which makes a gallon = 3785.411784 millilitres exactly.
