Knowledge And Teaching Research On Trigonometric Functions

Trigonometric function is one of the contents of the high school mathematics compulsory, it as a basis for computing tools, in other disciplines have different application, and also closely linked to the real life. Trigonometric function relative to the other knowledge, is a relatively independent discipline system, and so many concept and formula. Although the trigonometric function in the college entrance examination is not difficult, but because the student to grasp the concept, formula, the application is not very good, make the application of trigonometric function and combination with other knowledge points more difficult.This paper mainly studies the basic knowledge of trigonometric function and teaching content. First of all, according to the research status of triangle function, put forward in this paper, we study the purpose and significance; Second, according to the text summarizes the way of memory trigonometric function formula, facilitating students to understand the application. At the same time analyses the proportion score in college entrance examination questions type and, summarizes the university entrance exam, often two questions; By applying the teaching media and the course evaluation way, gives the teaching strategy; Finally, list some trigonometric function in the competition, university, and other aspects of the application, make the students have a new understanding of trigonometric function.The innovation point of this essay is for instance education media was used to explain, enriched classroom intuitive, easy to understand. And according to the middle school mathematics classroom teaching evaluation of class analysis, find out the advantages and disadvantages, to improve the quality of teaching in the teaching class later.
