Орта мектептегі стереометриялық есептерді шешуде векторлық-координаталық әдісін пайдаланудың тиімділігі туралы

Abstract

In order to increase the level of mathematical preparation of students in geometry lessons at school, it is necessary to pay special attention to the issue of good assimilation of the subject and ensuring high-quality preparation for the UNT in mathematics. The article discusses the vector-coordinate method, which is the main method for solving many geometric problems. Especially geometric problems of a metric nature. These methods lead a geometric problem to an algebraic problem. Application of the vector method in real situations requires mastering the following skills: translation of geometric language into vector language and vice versa; performing operations with vectors; write a vector as a product of a number and a vector, sum and difference of vectors; expression of the magnitude of the angle between vectors using a scalar product, etc. The vector-coordinate method does not require intuition, guesses, additional constructions: the solution of problems is algorithmized, which in most cases facilitates the solution of the problem. The effectiveness of using the vector-coordinate method in solving the problems of the BT is to solve complex problems for students in a limited time. By the example of solving a number of stereometric problems, the advantages of using the vector-coordinate method are shown. The content of the article will undoubtedly arouse the interest of university teachers, school teachers, high school students.
