In mathematics, "rational" is often used as a noun abbreviating "rational number". The adjective rational sometimes means that the coefficients are rational numbers. For example, a rational point is a point with rational coordinates (i.e., a point whose coordinates are rational numbers); a rational matrix is a matrix of rational numbers; a rational polynomial may be a polynomial with rational ...
The 6.5×68mm rebated rim bottlenecked centerfire rifle cartridge (also known as the 6.5×68mm RWS, 6.5×68mm Schüler, or the 6.5×68mm Von Hofe Express) and its sister cartridge the 8×68mm S were developed in the 1930s by August Schüler from the August Schüler Waffenfabrik, Suhl, Germany as magnum hunting cartridges that would just fit and function in standard-sized Mauser 98 bolt-action ...
A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...
Let p b be fraction of voters who voted exactly b (= v b / the total number of votes). A voting method is called homogeneous if it depends only on the fractions p b. So if the numbers of votes are all multiplied by the same constant, the method returns the same outcome. Phragmén's methods are homogeneous in that sense. [2]: Rem.2.1
Basis of trigonometry: if two right triangles have equal acute angles, they are similar, so their corresponding side lengths are proportional.. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) [1] are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
In the pendulum example the time measurements T are, in Eq(2), squared and divided into some factors that for now can be considered constants. Using rules for the transformation of random variables [ 5 ] it can be shown that if the T measurements are Normally distributed, as in Figure 1, then the estimates of g follow another (complicated ...
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
Smelting of iron ore into steel consumes 55% of commercially produced oxygen. [73] In this process, O 2 is injected through a high-pressure lance into molten iron, which removes sulfur impurities and excess carbon as the respective oxides, SO 2 and CO 2. The reactions are exothermic, so the temperature increases to 1,700 °C. [73]
