Notiunea de derivata a unei functii intr-un punct (lic_notiunederivata)

The notion of derivative of a function at a point, the derivation of elementary functions, online math video lessons Math video lessons for grades 5-12. In the channel's over 600 videos you will find definitions, properties, useful formulas as well as solved exercises, solved problems, topics or models for baccalaureate and national assessment. We have recently added more topics, models and solved variants for in-depth and quality preparation for the baccalaureate exams M1, M2 or national assessment. We are constantly adding other lessons and implicitly the exam topics in previous years will be added, trying to go as far as possible in time. Also, what you will find between our lessons and solved topics from the mathematics olympiads in the next editions, local, county, national stages for all grades. We aim to have materials for all categories of students, both those at an intermediate level and those capable and eager to perform. We are constantly adding solved exercises and solved problems. The project is of course a continuous effort to cover a vast subject, and if you feel that something is missing, you can communicate with us. We are trying with this project to respond as punctually as possible to the needs of the students, so any feedback helps. Thus, we propose a study of mathematics from natural numbers, rational numbers, irrational numbers, real numbers, equations and inequalities, equation setting problems, set operations, plane geometry to geometry in space, functions and functional dependencies, algebraic calculus, ratios of real numbers represented by letters, second degree equations and so on. Enjoy watching and success in your studies! We have recently added more topics, models and solved variants for a thorough and quality preparation for the M1, M2 or national assessment baccalaureate exams. We are constantly adding new lessons and implicitly the exam topics from previous years will be added (we already have a few), trying to go as far back in time as possible. You will also find among our lessons and solved topics from the mathematics olympiads from previous editions, local, county, national stages for all grades. We aim to have materials for all categories of students, both those at an average level and those capable and eager to perform. We are constantly adding solved exercises and problems. The project is of course a continuous effort to cover a vast subject, and if you feel that something is missing, you can communicate with us. We are trying with this project to respond as punctually as possible to the needs of the students, so any feedback helps. Thus, we propose a study of mathematics from natural numbers, rational numbers, irrational numbers, real numbers, equations and inequalities, problems to put into equations, operations with sets, plane geometry to geometry in space, functions and functional dependencies, algebraic calculus, ratios of real numbers represented by letters, second degree equations and so on. We have enough examples, exercises and solved problems of divisibility in the set of natural numbers, divisibility criteria, rules of calculation with powers, specific formulas, order of operations, ordinary fractions and decimal fractions, operations with fractions, simplification and amplification, irreducible fractions, periodic and mixed periodic decimal fractions, elements of geometry and units of measurement for lengths, time, volume, areas, etc. We also cover a good deal of plane geometry from the segment, the length of a segment, angles and angle measures, triangle congruence and triangle properties, to quadrilaterals, particular quadrilaterals (parallelogram, rectangle, rhombus, square), Thales' theorem, the fundamental similarity theorem, Pythagoras' theorem, the bisector theorem and others. Enough examples being a way of saying, we are never satisfied, we continue to work on others every day. Enjoy watching and good luck in your studies!
