clockwise
Direction f des aiguilles d'une montre

Clockwise direction of rotation. An indication of the direction of rotation in a surface. This is the direction similar to clockwise rotation.

ABC applies to 'A'B'C by turning 90° clockwise.


closed
fermé

closed . 1 - A group is closed during an operation when the combination of any two members of the group in the operation always results in a member of the original group.
For example: The set of natural numbers {...., 1,2,3,4} is a closed set in addition and multiplication, but it is not so in division and subtraction:

3÷1.5 = 2, which is not a natural number.
And 1-4 = -3, which is not a natural number.

2 - A closed curve is a curve that has no end points.

3 - The closed interval on the real number line is the set of all numbers, defined by inequalities of the type a < x < b.

The closed interval (3 > x 1 < x) is the set of all real numbers between the endpoints 1 and 3, including the two points themselves. It is indicated by [13].


coefficient
coefficient m

Factor . -1 - In simple algebra, the coefficient of a term is the numerical part of it. For example in:
4x2y + 3xy2-12x 9y
It is: the coefficient of 2y × equals 4
The xyz coefficient is equal to 3
Coefficient x equals 12 -
The y factor is equal to 9

2 - In science and engineering, the term is often used to refer to a specific numerical constant characteristic of a particular system, such as: the coefficient of linear expansion, the coefficient of friction...etc.


collinear
Colinéaire

Transcendent. Points are parallel if they lie on one straight line.

Points A, B, and C in the above diagram are coexistent points.

Notice the relationship between the vectors AB and BC, where: AB = 2BC.

Also note that there is a connection between the positions of vectors A, B and C.
OB = 1/30A++2/30C

And B divides the line segment AC in a ratio of 2 to 1.

column
colonne f

column . Vertical alignment of elements.
And the matrix
(613/427) It has three columns.
Choose from n or fewer objects from the set, regardless of order.

For example: The complete list of three-letter harmonics taken from the set (abcd) is: abc .bcd, acd, abd,

The number of harmonics r, a body that can be extracted from a set consisting of n bodies, is often referred to as: nCr or (n/r)

It can be shown that:

nCr = n ! /r! (n - r)!
where ! n means n factorial)

For example:
12C5 = 12! / 5! X 7! = 792

Note that 12C1 = 12C5, and in general the
nCr = nCn. 189r

The nCr values ​​of the variable r are the entries in the appropriate row of Pascal's triangle.


common denominator
Denominateur m commun

The common director (maqam). When preparing to add or subtract fractions with dissimilar denominators, the fractions are usually transformed into equivalent fractions with the same denominator, which is a common outcome.

1/3 + 1/2 - 2/6 + 3/6
That is, 6 is the common output (denominator).
