magic square
carré m magique

Square Magic square is an alignment of numbers such that the sum of each row, each column, and each of the diagonals is always the same. For example:

(A) (total 15)
(B) (total 52)

Table (B) above is very special because the sum of each quadrilateral block in the corners is 52 and the sum of the block of the four numbers in the center is 52 and the sum of each of the two small diagonals (29+6+1+16) and (2+17+8+5) is 52 and the sum of the four corners is 52 and the sum of the middle numbers in the upper and lower rows is 52 and the sum of the middle numbers in the left and right columns is 152.

magnitude
amplitude f

magnitude. The magnitude of a vector is its length when represented as a straight line segment.

In Pythagoras theorem, 32+42=52, so the expression here is 5.

major
grand

big. larger. 1 - The longest axes of symmetry in an ellipse are called the major axis. The other axis is called the minor axis. In the ellipse with the equation:

X2/a2 + y2/b2

The length of the major axis is 2a.

2 - The shaded section in the figure below shows the largest sector in the circle and the arc ACB is called the largest arc in the circle.

mapping
application f

Application. The application is a function. If we bisect each of the members of the set (8.6.4.2) a new set (4.3.2.1) is formed. Bisection transforms the members of one set into members of another set.

The figure shows what happens to the members 8.6.4.2. We say that the members of the set are mapped onto the members of the other set. The members 4,3,2,1 are called images 8,6,4,2.

The application or function is a special relationship in which each member of the set has one image.

The application diagram is just an illustration of it.

x>x+3

matrix
matrix f

A matrix is ​​a rectangular arrangement of members. For example:

Matrix A has two rows and two columns. Matrix B has two rows and three columns.

Matrixes that have the same order (i.e. have the same number of rows and columns) can be combined by adding the corresponding elements. For example:

Matrixes A and B are compatible for multiplication because A has the same number of columns as B. Multiplication involves adding the rows of A and the columns of B:

Square matrices that do not have zero determinants have multiplicative inverses:

Matrixes are a powerful tool for studying the solutions of linear equations.
