# Psychology is an independent variable

Axiom – statement taken 6es evidence.

Algebraic expression – a number of numbers, denoted by letters or numbers, and connected by the actions of addition, subtraction, multiplication, division, exponentiation and extraction of the root.

Abtsissa (french word). One of the points of Cartesian coordinates. Is the first. It is usually indicated by the symbol “X”. First used by G. Leibniz in 1675 (German scientist).

Additivity. Some property of values. He says the following: the value of a certain value corresponding to a full-fledged object is equal to the sum of values ​​of such a magnitude that correspond to its parts in any partition of the full-fledged object into parts.

Adjunct. Fully compliant with algebraic complement.

Axonometry. One of the ways to image on the plane of spatial figures.

Algebra. The part of mathematics that studies the problems and solutions of algebraic equations. The term was first seen in the 11th century. He applied the flies to honey ben-Musa al-Khorezmi (mathematician and astronomer).

Argument (function). Variable (independent) by which the function value is determined.

Arithmetic. The science that studies actions on numbers. Originated in Babylon, India, China, Egypt.

Asymmetry. Absence or violation of symmetry (inverse symmetry value).

Infinitely large – more than any predetermined number.

Infinitely small – less than any finite.

Billion. One thousand million (one with nine zeros).

Bisector. A beam having a beginning at the top of the corner (divides the angle into two parts).

Vector. The directed segment is straight. One end is the beginning of the vector; the other is the end of the vector. For the first time the term was used by W. Hamilton (Irish scholar).

Vertical angles. A pair of angles that has a common vertex (formed due to the intersection of two straight lines in such a way that the side of one angle is a direct continuation of the second).

Vector – a value characterized not only by its numerical value, but also by direction.

Schedule – a drawing that visually depicts the dependence of one quantity from another, a line that gives a visual representation of the nature of the change in function.

Hexahedron. Hexagon. The term was first used by Pappa of Aleksandiysky (ancient Greek scholar).

Geometry. The part of mathematics that studies spatial forms and relationships. The term was first used in Babylon / Egypt (5th century BC.).

Hyperbola. Unclosed curve (composed by two unbounded branches). The term appeared due to Appolonius of Perm (ancient Greek scholar).

Hypocycloid. This is the curve that the point of the circle describes.

Homotetia. The arrangement between the figures (similar), in which the straight lines connecting the points of these figures intersect at the same point (this is called the center of the homothety).

Degree. Unit of measure for a flat angle. Equal to 1/90 of a right angle. To measure angles in degrees beginning more than 3 centuries ago. For the first time such measurements were applied in Babylon.

Deduction. A form of thinking. With its help, any statement is derived logically (based on the rules of modern science of "logic").

Diagonal. A line segment that interconnects the vertices of a triangle (they do not lie on one side). For the first time used the term Euclid (3rd century BC).

Discriminant An expression composed of the quantities that define the function.

Fraction – A number composed of an integer number of units of one. It is expressed by the ratio of two integers m / n, where m is the numerator, showing how many fractions of a unit are contained in a fraction, and n is the denominator, indicating how many shares a unit is divided by.

Denominator. The numbers that make up the fraction.

Golden ratio – dividing the segment into two parts so that a large part belongs to a smaller one, as the whole segment to a large part. Approximately equal to
