In his Essai sur la théorie des nombres (1798), Adrien-Marie Legendre derives a necessary and sufficient condition for a rational number to be a convergent of the simple continued fraction of a given real number. [4] A consequence of this criterion, often called Legendre's theorem within the study of continued fractions, is as follows: [5 ...
This is a list of two-dimensional geometric shapes in Euclidean and other geometries. For mathematical objects in more dimensions, see list of mathematical shapes. For a broader scope, see list of shapes.
Entry of mixed fractions involves using decimal points to separate the parts. For example, the sequence 3. 1 5. 1 6 →cm converts 3 + 15 ⁄ 16 inches to 10.0 cm (approximately). The calculator may be set to automatically display values as mixed fractions by toggling the FDISP key. The maximum denominator may be specified using the /c function.
For example, it takes two dimensions to immerse (an equilateral triangle), and three to immerse (a regular tetrahedron) as shown to the right. dim K n = n − 1 {\displaystyle \dim K_{n}=n-1} In other words, the dimension of the complete graph is the same as that of the simplex having the same number of vertices.
So equivalence is defined by an integer Möbius transformation on the real numbers, or by a member of the Modular group (), the set of invertible 2 × 2 matrices over the integers. Each rational number is equivalent to 0; thus the rational numbers are an equivalence class for this relation.
For each of the types D 1, D 2, and D 4 the distinction between the 3, 4, and 2 wallpaper groups, respectively, is determined by the translation vector associated with each reflection in the group: since isometries are in the same coset regardless of translational components, a reflection and a glide reflection with the same mirror are in the ...

The closest pair of points problem or closest pair problem is a problem of computational geometry: given points in metric space, find a pair of points with the smallest distance between them. The closest pair problem for points in the Euclidean plane [ 1 ] was among the first geometric problems that were treated at the origins of the systematic ...
