الدرس:حل المعادلات من الدرجة الاولى ذات مجهول واحد

From 36.65 € /h

في هذا الدرس نعطي تعربفا للمعادلة من الدرجة الأولى بمجهول واحد و نتعرف على تقنية حل هذا النوع من المعادلات بإعتماد القواعد و الخاصيات التي تنظم حل المعادلات. في الأخير نتطرق غلى بعض المعادلات التي تؤول في حلها غلى معادلة من الدرجة الأولى بمجهول واحد.
تعريـــف :
a و b و x أعداد حقيقية .
كل متساوية على شكــل : ax + b = 0 تسمى معادلة من الدرجة الأولى بمجهول واحد هو x.
حل معادلة يعني إيجاد القيمة العددية للمجهول x التي تحقق المعادلة . مثلا حل المعادلة 2x - 6 = 0 هو 3 لأن :
0 = 6 - 3 × 2.
بصفة عامة :
** - إذا كان : a يخالف 0 و b يخالف فإن : للمعادلة ax + b = 0 حــلا وحيدا هو b/a-.
** - إذا كان : a يخالف 0 و b يساوي فإن : للمعادلة ax + b = 0 حــلا وحيدا هو العدد 0 .
** - إذا كان : a يساوي 0 و b يساوي فإن : للمعادلة ax + b = 0 عدة حلول .
** - إذا كان : a يساوي 0 و b يخالف فإن : المعادلة ax + b = 0 ليس لها حـــلا .

Je suis un professeur particulier de mathématiques qualifié et expérimenté. Diplômé de l'Université libre de Bruxelles en 2011, j'ai débuté ma carrière en dispensant des cours de remédiations dans différentes écoles de Bruxelles. Je me suis ensuite spécialisé dans le soutien scolaire individuel en suivant une formation pédagogique de la Harvard Graduate School of Education. Je donne des cours particuliers de mathématiques quotidiennement depuis plus d'une dizaine d'années.

Les élèves qui suivent mes cours particuliers bénéficient d'un accompagnement personnalisé. La première séance est consacrée à un bilan approfondi des connaissances en mathématiques de l'élève. L'objectif est de déceler ses points faibles et d'en comprendre leur origine afin d'adapter mes cours à ses besoins. J'élabore pour chacun de mes élèves un programme de remédiation sur-mesure visant à combler chacune de ses lacunes. Au fil des séances, l'élève construit des bases solides d'apprentissage et retrouve confiance en lui. Je l'aide en parallèle à acquérir une méthodologie de travail qui lui permet de devenir progressivement autonome dans ses études.

J'ai une parfaite connaissance du programme de mathématiques du Collège et du Lycée (de la Sixième à la Terminale). Je suis également qualifié pour accompagner les élèves dans la préparation des examens internationaux tels que le SAT, l'OMPT, ainsi que le Baccalauréat International (IB) dans toutes ses déclinaisons : Analysis and Approaches (AA SL/HL) et Applications and Interpretation (AI SL/HL).

Au cours de mes années de formation, j'ai étudié et développé de nombreuses techniques qui facilitent l'apprentissage des mathématiques. La force de mon approche pédagogique réside dans ma faculté à expliquer de façon simple tout ce que l'élève trouve compliqué. Je suis passionné par ce métier car il m'offre l'opportunité de guider des élèves en décrochage scolaire sur le chemin de la réussite. C'est un réel plaisir de les voir évoluer et se réconcilier avec le monde fantastique des mathématiques.

Je dispense mes cours particuliers à Paris (au domicile de l'élève) ou à distance (en ligne par internet). Mes cours à distance se déroulent sur un tableau blanc interactif en ligne. Ce tableau est spécialement conçu pour favoriser l'interaction élève/professeur sur internet. Grâce à cet outils pédagogique, mes cours en ligne sont aussi efficaces que des cours à domicile. L'élève a uniquement besoin d'une connexion internet et d'un ordinateur, une tablette, ou un smartphone pour en profiter.

Each session is thoughtfully designed to keep students interested and motivated, minimizing fatigue and maximizing retention.

I believe in simplifying complex topics, breaking them down into easy-to-understand segments. This approach helps students grasp and retain challenging concepts with ease. Techniques such as mnemonic devices, visual aids, and real-life examples are integral to my method, ensuring that formulas and concepts are not just memorized, but truly understood.

Regular assessments are conducted to track student progress and identify areas needing improvement. These tests also prepare students for their school exams, ultimately boosting their confidence. I understand the importance of keeping parents informed and involved in their child’s academic journey. That's why I provide weekly reports detailing their child’s progress, strengths, and areas for improvement. This continuous feedback loop ensures that parents are aware of their child’s development and can support their learning at home.

Encouraging words and positive feedback are integral to my teaching method. I strive to build students' self-confidence and to instill a love for learning through positive reinforcement. Setting achievable goals for each student, I celebrate their successes and motivate them to strive for excellence. This goal-setting approach not only drives academic success but also fosters a sense of accomplishment and self-worth.

As a tutor, my satisfaction comes from seeing my students excel and reach their full potential. My ultimate goal is to empower students with the knowledge and skills they need to succeed in Science and Maths. I am always available to support my students, offering additional help and resources as needed to ensure their success.

I foster an open environment where students feel comfortable asking questions, no matter how simple they may seem.

It is often thought that learning Mathematics is nothing more than memorizing formulas. In reality, learning Mathematics is about developing reasoning skills and building knowledge through sequences of logical steps.

In these personalized classes, we will cover topics from Arithmetic, Algebra, Trigonometry, and Analytical Geometry to Differential and Integral Calculus (Calculus I and II), always adapting the content to the student’s level, goals, and pace. These lessons are ideal both for strengthening foundational knowledge and for mastering more advanced topics. You will not only improve your grades; you should be able to explain some of the topics you initially struggled with to someone who doesn't even know them. That will demonstrate that you really understand the topic.
