abacus
abaque m

Abacus. A frame containing parallel wires that hold beads or small balls, and is used in calculations.

Chinese abacus
Higher column beads are worth five times as much
Bottom beads
The number shown here is 20,675


abscissa
abcisse f

First coordinate (sigmoid). The x coordinate of a point, or its distance from the axis - y axis in the Cartesian coordinate system.


absolute
absolu

Absolute. The absolute value of a real number is its numerical value regardless of its sign. The absolute value of the real number x [sometimes called modulus or mod xx] is written in the form, for example: 3.6=|3.6| And 9.1=|9.1-| .


acceleration
accélération f

Acceleration. The rate of change of velocity over time.
For example: If a body falls from a place with an acceleration of 9.8 meters per second, its speed, at every second between seconds 0 and 3, is shown in the table below:

Time (seconds) 3 - 2 - 1 - 0b
Speed ​​(meters per second) 29.4 - 19.6 - 9.8 - 0

If 7 is a vector representing speed, then the acceleration of the particle is a vector a obtained by differentiating a particle with respect to time.

a = dv /dt


acute
aigu

Sharp. Acute angle is an angle that measures between 0 and 90 degrees.

Sharp
Not sharp
Not sharp


addition
addition f

plural . One of the basic operations in airthmetic arithmetic. The sum of two numbers is determined by the addition process that is related to the accumulation process, such as: 3 + 2 = 5.

The word is used in abstract algebra to refer to operations that apply to different sets - for example - in the set of real matrices 2 × 2. The sum is defined as follows:


affine
affine

Consists . The affine transformation of a plane is a transformation that can be represented as follows:
Examples of these operations include: translation, rotation, shear, reflection, extension, and enlargement.

Under affine transformation, images of sets of parallel lines are themselves sets of parallel lines.


algebra
algèbre f

Algebra. Generalizing and representing significant results and patterns in arithmetic and other mathematical fields in a symbolic form such as: (43) (43) and also 92-52 (95) (95), both of which are examples of the algebraic equation: x+y) (x - y) = x2 -y2).


algorithm
algorithme f

Algorithm. A standardized (standard) process designed to solve a specific set of problems.
This is the usual algorithm for adding addition fractions of the formula:

W/X + W/Z

alternate
alterne

Mutual. Two angles are called alternate angles if they are on opposite sides of a transversal line that intersects two lines, and one of the two lines forms one of the two sides of each angle.
In the drawing below, angles A and C are considered alternate angles, as are angles B and D. The lines PQ and SR are parallel, and in this case their alternate angles are equal. That is, q = s and p = r.
