Les polynomes de second degre. Equations et inequations.

A partir de 26 $ /h

This is a chapter of the class of premiere in the French system. It deals with polynomials of the second degree.

We develop them using the discriminant.
We learn to factorize, study the sign, find the roots and even solving equations .
Iwill add more chapters for that class.
I will also translate it for students of the English system .But you can ask any question in the two languages freely. So contact me and I will send you the video of the course content.
We will then practice the exercises when you are ready.
Thank you

introduction to central symmetry and orthogonal symmetry

26 $ /h

This course introduces the notions of central symmetry and orthogonal symmetry. So we will learn the basic concept of symmetry about a point and symmetry about a line.
The students particularly concerned are those in the fifth grade of the French-speaking education system.
Of course, any other interested person would be welcome.

Graduated in mathematics and physics, I offer my help to students who encounter difficulties in these two subjects. My approach is to review with them the key points of the lessons and to assist them in their homework, whether at home or through online sessions via webcam.
Do not hesitate to contact me for a first request; I usually respond within 24 hours.
My goal is to help the student understand his course and his exercises, and to guide him on the right path so that he can succeed in his school or university year. I support students of all levels, from 14 years old to the second year of university, in the fields of science, economics or any other field where courses in mathematics, statistics, computer science and physics are exempted.
Classes can be given at home (with a price including the class and travel expenses) or by webcam (with a specific price for the online course).
For rehearsal sessions, I generally recommend between 1 and 2 hours per week, and up to 10 hours per week for intensive review and refresher courses.

Need a catch-up, tutoring, private lessons or help with homework in mathematics? In computer science ? In logic?
I'm here for you!
I offer you a personalized approach; because there is no one method that works for everyone, I adapt to the needs and requests of each student (and their parents). The first hour of class will be used to define the student's needs, deadlines and strengths.
My courses are aimed at secondary school students of all levels, higher education students and anyone wishing to refresh or strengthen their knowledge of mathematics and computer science. I have been helping friends and acquaintances on a voluntary basis for a long time in the success of their studies and I hope to be able to put this experience to the benefit of your success :)

(for English description see below)
Hi there,
I offer tutoring for math and science subjects here.
Regardless of whether it's school, university or work - having to learn to pass a subject is neither fun nor much point, as you'll soon forget most of it.
But how can it be better?
I have experienced several times how much of success depends on the emotions associated with learning. That's why I'll try to create an environment in which you feel free to make mistakes - because mistakes are important for learning! I rely on understanding, patience and curiosity to develop a positive relationship with learning rather than applying pressure.

Following the neurobiologist Gerald Hüther, I see the art in setting just the right big challenges to be exciting but not frightening, so that you automatically develop joy in discovery.
I would be happy to have an introductory meeting in order to take your needs and wishes into account from the outset.
Background information about me:
I am a qualified engineer (mechanical engineering) with 3 years of work experience, as well as a master's degree in bionics (cross-sectional discipline between biology and engineering) and a PhD in environmental protection of mountain regions. I was active as a youth leader at the Alpine Club.
I have been giving tutoring lessons on the side ever since I was at school.
I am pleased to meet you.

Whether you need help with homework, or would like to better understand various concepts that are covered in the curriculum, I am delighted to help!

First class will be to assess the level you are at and where you need assistance. Then we can start tackling whatever questions and problems you have.

I am here to help, and to guide you through the questions, but you are here to learn, not to have someone do the work for you, so I won't give you the answers, I will help you find them.

I have a BSc in Mathematics and am passionate about helping people to understand and enjoy the subject.

With a background in Civil Engineering, I offer private tutoring in mathematics and science for all primary and secondary school levels. Each student has specific needs, which is why I adopt a flexible and supportive approach. My goal is to help students understand concepts in depth, build confidence, and progress effectively. During the lesson, we begin with a discussion to identify difficulties and define appropriate objectives together. Next, a theoretical review consolidates the foundations before moving on to progressive exercises, encouraging the practical application of the concepts covered. Throughout the session, I encourage students to rephrase concepts and place them in a logical context to solidify their learning. Finally, we take a few minutes to review the session and write a summary of the key points to facilitate revision and memorization. I offer online courses and emphasize the value of online teaching by using interactive tools, screen sharing, and adapted materials to ensure the same clear and effective support as in face-to-face sessions. In addition to the lessons, I offer personalized follow-up with the option of reviewing exercises remotely between classes. Whether you need regular support or occasional help before an exam, I would be delighted to help you progress in a motivating and supportive environment!
