The silver ratio is a Pisot–Vijayaraghavan number (PV number), as its conjugate 1 − √ 2 = −1 δS ≈ −0.41421 has absolute value less than 1. In fact it is the second smallest quadratic PV number after the golden ratio. This means the distance from δ n. S to the nearest integer is 1 δ n.
In mathematics, the supersilver ratio is a geometrical proportion close to 75/34. Its true value is the real solution of the equation x 3 = 2 x 2 + 1. The name supersilver ratio results from analogy with the silver ratio , the positive solution of the equation x 2 = 2 x + 1 , and the supergolden ratio .
Just diatonic semitone on C: 16 15 = 15 + 1 15 = 1 + 1 15 Play ⓘ. In mathematics, a superparticular ratio, also called a superparticular number or epimoric ratio, is the ratio of two consecutive integer numbers. More particularly, the ratio takes the form: where n is a positive integer. Thus:
The golden ratio is also an algebraic number and even an algebraic integer. It has minimal polynomial. This quadratic polynomial has two roots, and. The golden ratio is also closely related to the polynomial. which has roots and As the root of a quadratic polynomial, the golden ratio is a constructible number.
The metallic mean (also metallic ratio, metallic constant, or noble means[1]) of a natural number n is a positive real number, denoted here that satisfies the following equivalent characterizations: the unique positive real number such that. the positive root of the quadratic equation. the number.
Adjusting these figures, in the grey powder there is about 13.5 g of oxygen for every 100 g of tin, and in the white powder there is about 27 g of oxygen for every 100 g of tin. 13.5 and 27 form a ratio of 1:2. These compounds are known today as tin(II) oxide (SnO) and tin(IV) oxide (SnO 2). In Dalton's terminology, a "protoxide" is a molecule ...

Two functions and () are proportional if their ratio () is a constant function. If several pairs of variables share the same direct proportionality constant, the equation expressing the equality of these ratios is called a proportion , e.g., a / b = x / y = ⋯ = k (for details see Ratio ).
