Euler's formula
formule f d'Euler

Euler's formula. In the case of networks:

4 nodes
4 starting points
6 arcs
Nodes + starting points = arcs + 2

In the case of polyhedra:

5 faces
5 vertices
8 letters
Faces + vertices = letters + 2

even
pair

Even. Numbers whose factor is 2 are called even numbers. Even numbers are multiples of 2: 2, 4, 6, 8, etc.

expansion
développement m

Publish the expanded or extended form of an expression. Example:

x3+3x2+3x+1( is (x+1)3 if the

exponent

exposant m

Exponent. The power of the exponent is the numerical symbol used
to indicate raising a base number to a specified power. For example: the exponent of 34 is 4.

exponential

exponentiel

Exponent. A term applied to functions of the type ax=f(x). All functions of this type have certain common characteristics. For example, they are positive no matter what, and they tend to zero as they become more negative, and their graphs intersect the y-axis at 1, i.e. 1= (0)f.

The function ex = (f(x) is specifically known as the exponential function. These functions are accompanied by natural growth and decay. They are the opposite of logarithmic functions.

extrapolate
extrapoler

Extension. Using past numbers to predict the future. In the drawing The graph below attempts to predict the population of Great Britain in 1911 by counting them over the period 1821-91.
