基本不等式 - 宽正校园（Basic inequality - width positive campus）

基本不等式 - 宽正校园（Basic inequality - width positive campus） Trigonometric function image transformation (first class) Today Im going to talk about trigonometric function transformation (first class). I will analyze and explain it from the following aspects: teaching material analysis, teaching objective, teaching method, teaching process and so on. I. Analysis of teaching materials 1, status and role This section is the content of the first fifth chapters of the 4 chapter, which is the basic knowledge of trigonometric functions, and is an important model for the integration and application of the problem. It has a very important significance in teaching materials, and it is a bridge between theoretical knowledge and practical problems. Students learn the function y=Asin (omega x+ phi) image, which provides a mathematical model for the high school physics research, pendulum movement, harmonic motion, mechanical waves and so on. 2, teaching difficulties Teaching emphasis: To investigate the influence of parameter Omega, phi and A on function image, and to understand the change process of y=sinx image to y=Asin (omega, x+, phi) image. Teaching difficulty: the discovery and generalization of the influence law of y=Asin (omega, x+, phi) image is the difficult point of this lesson. Two, teaching objectives Knowledge and skills: 1) the relationship between y=Asinx, y=sin, Omega, x, y=sin (x+, phi) and y=sinx images is revealed by drawing images 2) further study on comprehensive transformation is composed of alpha Phi Omega transform, transform, transform, make the function y = Asin (omega phi X) image; Objective and methods: To explore the experience of cultivating the students ability and ability of exploring the problems and Shuxingjiege thinking; understand from special to general, from concrete to abstract thinking so as to achieve from perceptual knowledge to rational knowledge leap. Emotions, attitudes, values, goals: through the learning process, students explore the spi
