In mathematics there are many types of numbers depending on the characteristics they have. In this numerical typology, integers can be mentioned, which are those that do not have a decimal part and include natural numbers, zero and negative numbers . The notion of whole numbers was established to refer to indivisible units such as a person or a country. What are … Read more
In the history of geometry, Euclid of Alexandria is the main representative of this science. His contributions to humanity are invaluable and many of them remain today as universal premises. By many mathematicians and geometricians, he is known as the father of geometry . Euclid along with Archimedes and Apollonius of Perga is part of the triad of mathematicians of antiquity and is one … Read more
In mathematics, numbers can be classified according to their characteristics and use. The rational numbers represent the set of numbers that can be split to discuss parts of a whole. These numbers are frequently used to represent measurements in different areas such as architecture, medicine, chemistry, biology, etc. What are rational numbers? Rational or fractional numbers are those that can be described through … Read more
A special type of polygons is known as a parallelogram . This is a quadrilateral where both pairs of opposite sides are parallel . The word has its origin in the Latin word parallelogrammus , and this concept helps us to identify a quadrilateral in which the opposite sides are parallel to each other. This geometric figure constitutes is then formed by a polygon that is made up … Read more
Triangles are polygons that are made up of three sides, so we can say that the triangle is a flat figure that is made up of three different segments . What is the right triangle? The right triangle is the triangle that has a right angle which has a measure of 90 degrees and two angles that are acute , which means that they measure less than ninety … Read more
The cosecant function is an old function in the area of mathematics . It was mentioned in the works of GJ von Lauchen Rheticus in 1596 and E. Gunter around 1620. It was widely used by L. Euler in 1748 and T. Olivier, Wait and Jones in 1881. The classical definition of function cosecant for real arguments is: “the cosecant of an angle in … Read more
The application of trigonometric functions in the area of mathematics and in other areas is widely used in our world. These functions are one of the basic mathematical functions in areas such as triangulation , which is used in criminal investigations and cell service . They are also used in navigation, surveying , computer graphics , and music theory . And one of the most important areas is the cotangent trigonometric function . What is the cotangent? The … Read more
In the set of real numbers, there are rational and irrational numbers. The latter cannot be expressed as a fraction and can be of two types, algebraic or transcendental. The irrational numbers are those that can not be expressed in fractions that contain decimal indeterminate elements and are used in complex mathematical operations as algebraic equations and physical formulas. What are irrational numbers? Irrational … Read more
Within the set of real numbers we can find different types of numbers such as rational and irrational numbers, which in turn can be subdivided into others, among which we can mention the algebraic numbers that are the set of numbers that appear as a result of an algebraic equation . They cannot be expressed in fractions and can represent … Read more
In the history of mathematics Diophantus of Alexandria is known as the father of master algebra for his works and the contributions he left to this science of numbers. By his skill in calculation, he managed to produce a large collection of problems of this type and solve them without making use of Euclidean geometry . All these problems were compiled in his … Read more
