  2. Rational root theorem - Wikipedia

    en.wikipedia.org/wiki/Rational_root_theorem

    The theorem is used to find all rational roots of a polynomial, if any. It gives a finite number of possible fractions which can be checked to see if they are roots. If a rational root x = r is found, a linear polynomial ( x – r ) can be factored out of the polynomial using polynomial long division , resulting in a polynomial of lower degree ...

  3. Power of 10 - Wikipedia

    en.wikipedia.org/wiki/Power_of_10

    m × 10 n. Or more compactly as: 10 n. This is generally used to denote powers of 10. Where n is positive, this indicates the number of zeros after the number, and where the n is negative, this indicates the number of decimal places before the number. As an example: 10 5 = 100,000 [1] 10 −5 = 0.00001 [2]

    Obreschkoff–Ostrowski theorem: in blue and yellow, the regions of the complex plane where there should be no root for having 0 or 1 sign variation; on the left the regions excluded for the roots of p, on the right, the regions excluded for the roots of the transformed polynomial q; in blue, the regions that are excluded for having one sign ...

  5. Zeros and poles - Wikipedia

    Its zeros in the left halfplane are all the negative even integers, and the Riemann hypothesis is the conjecture that all other zeros are along Re(z) = 1/2. In a neighbourhood of a point , a nonzero meromorphic function f is the sum of a Laurent series with at most finite principal part (the terms with negative index values):

  6. Descartes' rule of signs - Wikipedia

    en.wikipedia.org/wiki/Descartes'_rule_of_signs

    In particular, when the number of sign changes is zero or one, then there are exactly zero or one positive roots. A linear fractional transformation of the variable makes it possible to use the rule of signs to count roots in any interval. This is the basic idea of Budan's theorem and the Budan–Fourier theorem. Repeated division of an ...

  7. Windows Calculator - Wikipedia

    en.wikipedia.org/wiki/Windows_Calculator

    The Calculator in non-LTSC editions of Windows 10 is a Universal Windows Platform app. In contrast, Windows 10 LTSC (which does not include universal Windows apps) includes the traditional calculator, but which is now named win32calc.exe. Both calculators provide the features of the traditional calculator included with Windows 7 and Windows 8.x ...

  8. Hilbert's Nullstellensatz - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_Nullstellensatz

    In mathematics, Hilbert's Nullstellensatz (German for "theorem of zeros", or more literally, "zero-locus-theorem") is a theorem that establishes a fundamental relationship between geometry and algebra. This relationship is the basis of algebraic geometry. It relates algebraic sets to ideals in polynomial rings over algebraically closed fields.
