ARC COS - The inverse cosine function. If y = cos x, then x = arc cos y.
ARC COTG - The inverse function of the cotangent. If y = cotg x, then x = arc cotg y.
CURVE BOW - Part of a curve situated between any two points of the curve. If A and B are any two points of a circumference, there are two arcs AB, these arcs are of different lengths if A and B are not extreme points in diameter, the largest is called the major arc and the other is the smaller arc.
ARC SEN - The inverse function of sine. If y = sen x, then x = arc sen y.
ARC TG - The inverse function of the tangent. If y = tg x, then x = arc tg y.
AREA - Measurement of a surface.
ARESTA - The intersection of two faces of a solid. In the attached drawing, it is the line segment that represents the intersection of two faces.
ARITHMETIC - Part of mathematics that studies numbers and operations.
ROUND - Approximate the value of a number.
ASSOCIATIVE - Law that allows to group the terms of an addition or multiplication without changing the result. Multiplication and addition are associative operations.
(A + B) + C = A + (B + C)
(A × B) × C = A × (B × C)
ATTRIBUTE - A quality or characteristic of a mathematical object.
AUTOMORPHISM - Isomorphism that transforms a figure into itself.
GRANDPARENTS - Names fractions of denominators greater than 10, but different from 100, 1000, etc.
AXIOMA - Proposition accepted as initial truth not demonstrable by its evidence.
