altitude
hauteur f

to rise . The height of a triangle is the perpendicular distance between the vertex of the triangle and the opposite side called the base.

In the above two triangles, AC is the base, and the distance BD is the height.

The area of ​​any triangle can be calculated by multiplying 1/2 the length of the base by the height.
Note: The three altitudes of any triangle pass through one common point.


amplitude
amplitude f

Capacity. The amplitude in a vibrating movement is a measure of the maximum displacement from the center line or the base position.

For the periodic function f (x) = 3sinx periodic function, the amplitude is equal to 3.


analysis
analyze f

analysis . The branch of mathematics that is concerned with precise proofs of assumptions, especially in the field of calculus.


angle. angle
angle m

corner . The angle between two lines is the measurement of the slope of one of them with respect to the other. On the other hand, the angle can be viewed as a measurement of the rotation (around the point of intersection) of the two lines necessary for one line to fit over the other.

Small angle
Larger angle

The two most common angle measurements are degrees and radians.


annulus
anneau m

episode . The ring originates from a region of a plane surrounded by two concentric circles.

The starting point is a loop.
If 2 and R are the radials of the two circles and r < R, then the area of ​​the ring is:


antilogarithm
antilogarithme m

versus logarithm. Inverse logarithm fucntion. It is used in particular when base 10 logarithms are used specifically for arithmetic purposes. For example:

log10 100 = 2
antilog10 2 = 100


apex
sommet m

head . The highest point of a solid or plane in relation to the base plane or its line.


approximation
approximation f

Approximation . An approximation is a result that is not perfectly precise but is accurate enough for certain purposes.

For example, the square root closest to the decimal place of 2 is 1.4, and the percentile is 1.41.

The study of the processes of rounding various formulas constitutes an important branch of mathematics.
For example: Taylor's Theorem provides a way to approximate certain functions by polynomials.

Newton's method provides an iterative method for obtaining approximations to the roots of certain equations.
