inequality
inéqalité f

Inequality. Prevalence. Inequality or arrangement is a mathematical statement that one quantity is greater than or less than another quantity.
For example:

2<3(3 is greater than 2).

4 > 1 (1 is less than 4).
X > 1
X is greater than or equal to 1

y < 2
y is less than or equal to 2

Inequalities remain valid if one quantity is added to or subtracted from both sides, or if both sides are multiplied or divided by the same positive quantity. However, multiplying or dividing by a negative number changes the direction of the inequality.

inequation
inéquation f
اليقان قات سودة

Inequality. A statement that includes inequalities, for example:
x²+2x+2>0

This inequality holds for all numerical values ​​of x.

And y>3x-1 holds for all points below the line.

y=3x-1

infinite
infini

Infinite. A quantity is said to be infinite when this quantity is greater than any specific limit. For example: the set (1,2,3,4) has an infinite number of members. As for the set .....a,b,c, it has a finite number of members because it can be counted (26 members).

The symbol 55 is used to represent the infinite value or
infinity.

inflection
inflexion f

Inflection. The inflection point on a curve is the point at which the curve changes from concave upward to concave downward (or vice versa). The point P in the drawing is called a stationary point of inflection since the gradient of point P is zero. Q represents a non-stationary inflection since the gradient is not zero at Q.

A tangent intersects the curve at the inflection point.

inscribed
inscrit

inscribed. A circle is inscribed by a polygon if all sides of the polygon are tangent to the circle.

The center of a circle inscribed by a triangle is the point of intersection of the angle bisectors.

integer
entier m

integer. See whole numbers.

integral
intégrale f

integral. The integral of a function (f(x) is defined as the limit as 8x approaches zero of the sum of the areas of the rectangles under the curve (see figure below).

The area under the curve between the values ​​x=a and x=b is written as:

f(x) dx

This is called a definite integral, and a and b are known as the lower and upper limits of the integral.

Any function whose derivative f(x) is called an indefinite integral of f (x).


integration
intégration f

Integration is the process of finding a definite or indefinite integral. Integration can be thought of as the opposite of differentiation.
