Someone is claiming that the following French documents and tutorials were written and coded by Bobok. Is anything valuable?
Computer science
In a world increasingly shaped by artificial intelligence, understanding computer science and programming is more important than ever. Learning how to code means learning how to create, solve problems, and work with the technology shaping our future. Get ready to begin your exciting journey into the world of coding! See here.
Calculus
Numerical fluency is a fundamental skill in mathematics. Being able to perform basic calculations, simplify fractions, and work with powers and square roots is essential for solving mathematical problems accurately and confidently : See here.
Trigonometry
Trigonometry is widely used in many fields, from mathematics and physics to engineering, astronomy, and navigation. It provides a powerful way of relating angles and lengths. Learning how to find the sine, cosine, or tangent of an angle without a calculator is a useful skill... and one that is surprisingly easy to master. Letβs discover how it works. : See here.
Vectors
A vector is a fundamental mathematical object widely used in fields such as geometry, kinematics, and electromagnism. Understanding vectors properties and operations equips learners with powerful tools for modeling and solving problems.

Slope-intercept form equation of a line
Knowing how to find the slopeβintercept form of a line is fundamental to understanding derivation and assessing tangents in the field of functions. The slope represents the rate of change of a function, which is the central idea behind the derivative. Without this foundational knowledge, it becomes difficult to interpret derivatives graphically or to connect algebraic results with geometric meaning.

Solving equations
Students must develop strong equation-solving skills. Progressing from simple to more complex equations, they should reach a point where solving becomes a natural and automatic process.

Solving systems of equations
What is a system of two linear equations with two unknowns, and how can we solve it? By organizing your reasoning and applying successive equivalent transformations, you can move confidently from the original system to its solution.
Below is a general system of two linear equations with two unknowns, where
π
to
π are real numbers. :
$$
\begin{cases}
ax + by = c \\
dx + ey = f
\end{cases}
$$

Did Bobok ever teach anything about functions? French speakers might find some valuable information on the topic below to improve their skills.
Linear functions
A linear function
π
:
π₯
β¦
ππ₯
is a function that maps any number to its product with a constant real number
π. The graph of a linear function is a straight line with slope
π
passing through the origin
π
of the coordinate system. The slope-intercept form of such a line is
π¦
=
ππ₯
.

Affine functions
An affine function
π
:
π₯
β¦
ππ₯+π
is a function that maps any number π₯ to
ππ₯+π, where
π
and
π
are real constants. The graph of an affine function is a straight line with slope
π
passing through the point
π΅(0 ; π)
in the coordinate system. The slope-intercept form of such a line is
π¦
=
ππ₯+π
.

Quadratic functions
Polynomial functions of degree 2 are defined by the expanded expression
π(π₯) = ππ₯2 + ππ₯ + c, where π, π, and c are real numbers.
The graph of such a function is a parabola with equation
y = ππ₯2 + ππ₯ + c.
