The ratio of the hypotenuse to a leg is represented by c:b. Assume a, b, and c are in the smallest possible terms (i.e. they have no common factors). By the Pythagorean theorem: c 2 = a 2 +b 2 = b 2 +b 2 = 2b 2. (Since the triangle is isosceles, a = b). Since c 2 = 2b 2, c 2 is divisible by 2, and therefore even. Since c 2 is even, c must be even.
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 tonalities of the six Partitas (B ♭ major, C minor, A minor, D major, G major, E minor) may seem to be random, but in fact they form a sequence of intervals going up and then down by increasing amounts: a second up (B ♭ to C), a third down (C to A), a fourth up (A to D), a fifth down (D to G), and finally a sixth up (G to E).

A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number (such as 16361) that remains the same when its digits are reversed.In other words, it has reflectional symmetry across a vertical axis.
Dyadic rationals in the interval from 0 to 1. In mathematics, a dyadic rational or binary rational is a number that can be expressed as a fraction whose denominator is a power of two.
If a given digit is on the left hand side of the radix point (i.e. its value is an integer) then n is positive or zero; if the digit is on the right hand side of the radix point (i.e., its value is fractional) then n is negative.
Europeans first learned of Arabic numerals c. the 10th century, though their spread was a gradual process. After Italian scholar Fibonacci of Pisa encountered the numerals in the Algerian city of Béjaïa, his 13th-century work Liber Abaci became crucial in making them known in Europe.
The Partita for keyboard No. 2 in C minor, BWV 826, is a suite of six movements written for the harpsichord by Johann Sebastian Bach. It was announced in 1727, [ 1 ] issued individually, and then published as Bach's Clavier-Übung I in 1731.
