Lithuanian Language
Lithuanian (, ) is an East Baltic languages, East Baltic language belonging to the Baltic languages, Baltic branch of the Indo-European language family. It is the language of Lithuanians and the official language of Lithuania as well as one of the official languages of the European Union. There are approximately 2.8 million native Lithuanian speakers in Lithuania and about 1 million speakers elsewhere. Around half a million inhabitants of Lithuania of non-Lithuanian background speak Lithuanian daily as a second language. Lithuanian is closely related to neighbouring Latvian language, Latvian, though the two languages are not mutually intelligible. It is written in a Latin script. In some respects, some linguists consider it to be the most conservative (language), conservative of the existing Indo-European languages, retaining features of the Proto-Indo-European language that had disappeared through development from other descendant languages.

Conic Sections
A conic section, conic or a quadratic curve is a curve obtained from a Conical surface, cone's surface intersecting a plane (mathematics), plane. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though it was sometimes considered a fourth type. The Greek mathematics, ancient Greek mathematicians studied conic sections, culminating around 200 BC with Apollonius of Perga's systematic work on their properties. The conic sections in the Euclidean plane have various distinguishing properties, many of which can be used as alternative definitions. One such property defines a non-circular conic to be the set (mathematics), set of those points whose distances to some particular point, called a ''Focus (geometry), focus'', and some particular line, called a ''directrix'', are in a fixed ratio, called the ''Eccentricity (mathematics), eccentricity''. The type of conic is determined by the value of the ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arithmetic
Arithmetic is an elementary branch of mathematics that deals with numerical operations like addition, subtraction, multiplication, and division. In a wider sense, it also includes exponentiation, extraction of roots, and taking logarithms. Arithmetic systems can be distinguished based on the type of numbers they operate on. Integer arithmetic is about calculations with positive and negative integers. Rational number arithmetic involves operations on fractions of integers. Real number arithmetic is about calculations with real numbers, which include both rational and irrational numbers. Another distinction is based on the numeral system employed to perform calculations. Decimal arithmetic is the most common. It uses the basic numerals from 0 to 9 and their combinations to express numbers. Binary arithmetic, by contrast, is used by most computers and represents numbers as combinations of the basic numerals 0 and 1. Computer arithmetic deals with the specificities of the ...

Trigonometry
Trigonometry () is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios (also called trigonometric functions) such as sine. Throughout history, trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics, and navigation. Trigonometry is known for its many identities. These trigonometric identities are commonly used for rewriting trigonometrical expressions with the aim to simplify an expression, to find a more useful form of an expression, or to solve an equation.

Geometry
Geometry (; ) is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a ''List of geometers, geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point (geometry), point, line (geometry), line, plane (geometry), plane, distance, angle, surface (mathematics), surface, and curve, as fundamental concepts. Originally developed to model the physical world, geometry has applications in almost all sciences, and also in art, architecture, and other activities that are related to graphics. Geometry also has applications in areas of mathematics that are apparently unrelated. For example, methods of algebraic geometry are fundamental in Wiles's proof of Fermat's Last Theorem, Wiles's proof of Fermat's ...

Binomial Theorem
In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial. According to the theorem, the power expands into a polynomial with terms of the form , where the exponents and are nonnegative integers satisfying and the coefficient of each term is a specific positive integer depending on and . For example, for , (x+y)^4 = x^4 + 4 x^3y + 6 x^2 y^2 + 4 x y^3 + y^4. The coefficient in each term is known as the binomial coefficient or (the two have the same value). These coefficients for varying and can be arranged to form Pascal's triangle. These numbers also occur in combinatorics, where gives the number of different combinations (i.e. subsets) of elements that can be chosen from an -element set. Therefore is usually pronounced as " choose ". Statement According to the theorem, the expansion of any nonnegative integer power of the binomial is a sum of the form (x+y)^n = x^n y^0 + x^ y^1 + x^ y^ ...

Christian Wolff (philosopher)
Christian Wolff (; less correctly Wolf, ; also known as Wolfius; ennobled as Christian Freiherr von Wolff in 1745; 24 January 1679 – 9 April 1754) was a German philosopher. Wolff is characterized as one of the most eminent German philosophers between Leibniz and Kant. His life work spanned almost every scholarly subject of his time, displayed and unfolded according to his demonstrative-deductive, mathematical method, which some deem the peak of Enlightenment rationality in Germany. Wolff wrote in German as his primary language of scholarly instruction and research, although he did translate his works into Latin for his transnational European audience. A founding father of, among other fields, economics and public administration as academic disciplines, he concentrated especially in these fields, giving advice on practical matters to people in government, and stressing the professional nature of university education.

Navahrudak
Novogrudok or Navahrudak (; ; , ; ) is a town in Grodno Region, Belarus. It serves as the administrative center of Novogrudok District. As of 2025, it has a population of 27,624. In the Middle Ages, the city was ruled by King Mindaugas' son Vaišvilkas. During and after Mindaugas' rule, Novogrudok was part of the Kingdom of Lithuania, and later the Grand Duchy of Lithuania, which was later part of the Polish–Lithuanian Commonwealth. In the 14th century, it was an episcopal see of the Metropolitanate of Lithuania. From 1795 to 1915, the Russian Empire ruled over the lands, with brief periods of intercession, e.g. Napoleon's ''Grande Armée'' in 1812 and the Uprisings of 1831 and 1863. After 1915, Novogrudok was occupied by the Imperial German Army for three years in World War I, by the Second Polish Republic until the Soviet invasion of Poland in 1939. Thereafter, the Soviet Union annexed the area to the Byelorussian SSR. From 1941 to 1944, Novogrudok was occupied by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vilnius University
Vilnius University ( Lithuanian: ''Vilniaus universitetas'') is a public research university, which is the first and largest university in Lithuania, as well as one of the oldest and most prominent higher education institutions in Central and Eastern Europe. Today, it is Lithuania's leading research institution. The university was founded in 1579 as the Jesuit Academy (College) of Vilnius by Stephen Báthory. It was the third oldest university (after the Cracow Academy and the Albertina) in the Polish–Lithuanian Commonwealth. Due to the failure of the November Uprising (1830–1831), the university was closed down and suspended its operation until 1919. In the aftermath of World War I, the university saw failed attempts to restart it by the local Poles, Lithuanians, and by invading Soviet forces. It finally resumed operations as Polish Stefan Batory University in August 1919. After the Soviet invasion of Poland in September 1939, the university was briefly administered by t ...
