Andrea Amati (ca. 1505 - 1577, Cremona) was a luthier, from Cremona, Italy. [1] [2] Amati is credited with making the first instruments of the violin family that are in the form we use today. [3] Several of his instruments survive to the present day, and some of them can still be played.
A claim that Andrea Amati received the first order for a violin from Lorenzo de' Medici in 1555 is invalid as Lorenzo de' Medici died in 1492. A number of Andrea Amati's instruments survived for some time, dating between 1538 (Amati made the first Cello called "The King" in 1538) and 1574.
For example, the polynomial +, which can also be written as +, has three terms. The first term has a degree of 5 (the sum of the powers 2 and 3), the second term has a degree of 1, and the last term has a degree of 0. Therefore, the polynomial has a degree of 5, which is the highest degree of any term.
In mathematics and other formal sciences, first-order or first order most often means either: " linear " (a polynomial of degree at most one), as in first-order approximation and other calculus uses, where it is contrasted with "polynomials of higher degree", or
The order polynomial counts the number of order-preserving maps from a poset to a chain of length . These order-preserving maps were first introduced by Richard P. Stanley while studying ordered structures and partitions as a Ph.D. student at Harvard University in 1971 under the guidance of Gian-Carlo Rota.
Cello: with 'The King Violoncello' by Andrea Amati being the earliest known bass instrument of the violin family to survive. [55] Centrifugal Pump: the first machine that could be characterized as a centrifugal pump was a mud lifting machine that appeared as early as 1475 in a treatise by the Italian Renaissance engineer Francesco di Giorgio ...
the multiplicative order, that is, the number of times the polynomial is divisible by some value; the order of the polynomial considered as a power series, that is, the degree of its non-zero term of lowest degree; or; the order of a spline, either the degree+1 of the polynomials defining the spline or the number of knot points used to ...
Low-order polynomials tend to be smooth and high order polynomial curves tend to be "lumpy". To define this more precisely, the maximum number of inflection points possible in a polynomial curve is n-2, where n is the order of the polynomial equation. An inflection point is a location on the curve where it switches from a positive radius to ...
