trajectory
trajectoire f

Path. The path taken by a moving body, often used in reference to bodies moving under the influence of the Earth's gravitational field (or the gravity of another large body).

transcendental
transcendant

Transcendent. Irrational numbers, such as π and e, that cannot be obtained as a result of solving a polynomial equation with area coefficients are called transcendental numbers.

Other numbers, including irrational ones, that can be obtained as a result of solving such equations are called algebraic numbers. 2=x2 has a solution of 2, so 2 is an algebraic number.

transformation
transformation f

Transformation. A change in spatial or algebraic work involving mapping one shape or space onto another, or one expression onto another, often by substitution.

The study of different types of transformations, such as rotation, translation, etc., is central to work in algebra and geometry.

transitive
transitif

Transitive. A relation R between elements of a set has the property of transitivity in the following case:

When there is a relation between the elements x, y, and z, such as XRY and YRZ, and the relation XRZ is satisfied. For example: The relation greater than defined on a set of real numbers is transitive because 6<7 and 4<6 means that 7 > 4. The relation |(half so) defined on a set of real numbers is not transitive because 3|6 and 6|12, but this does not mean that 12|3.

translation
translation f

Translation. A geometric transformation of a plane or a space of the form: x → x+a and
y →y+b and z → z+c, etc.

Translation is equivalent to referring to a set of new axes parallel to the original set.
The translation operations are often written in vector form, in which case:

The image of the figure after the translation is congruent with the original figure.

transpose
transposition f

Transposition. A transposition of a matrix M is achieved by swapping the rows and columns of the matrix.

transversal
transversal

Transverse. A name given to a line that intersects a given set of lines.

trapezium
trapèze m

trapezium. A trapezium is a quadrilateral with two parallel sides.

If the lengths of the parallel sides are a and b and they are separated by a distance h, the area of ​​the trapezium A is:
A = (a + b) x h/2

tree diagram
arbre m

Tree diagram. A diagram used to represent complex events and to enable their probabilities to be evaluated.

The tree diagram below represents the eight possible outcomes of tossing a coin three times.

(Heads) Head. (Tails) Tail

The probabilities of individual events are indicated on the appropriate branches of the tree, and the probability of a compound event such as tail (tails), then head (tails), then tail (tails) can be calculated by multiplying the probabilities along the branches.
Probability of tail (tails) - head (tails) - tail (tails) =

1/2×1/2×1/8 = 1/2

trial
épreuve f

A trial. A trial is a repetition of a particular experiment under controlled conditions in a statistical investigation.
