教材分析:定积分的应用是在学生学习了定积分的概念、定积分的计算,了解、掌握定积分的几何意义之后,对定积分知识的总结和升华,通过用定积分解决一些简单曲边多边形的面积问题,使学生初步感受定积分在解决数学问题与实际问题中的作用,体会导数与定积分之间的内在联系.教师在教学时,应紧扣课本,注意深度和广度.教学目标:【知识与技能】通过本节课的学习,学生能够应用定积分解
Teaching material analysis: The application of definite integral is that the student learns the concept of definite integral, the definite integral computes, understands, grasps the definite meaning of definite integral, summarizes and sublimates the definite integral knowledge, by using fixed integral to solve some simple curved edges The area of polygons will enable students to initially experience the role of definite integral in solving mathematical problems and practical problems and to understand the intrinsic relationship between derivatives and definite integrals.Teaching teachers should closely follow the textbooks and pay attention to the depth and breadth of their teaching. : [Knowledge and Skills] Through the study of this lesson, students can apply the Decomposition
