“在知识网络交汇点处设计试题,使对数学基础知识的考查达到必要的要求.”这是高考命题的一个重要思想.定积分作为高中新课程新增内容之一,它的重要应用之一是求曲边梯形的面积,而高考多半在定积分与其它数学知识交汇处命制试题.兹分类例说如下.一、定积分与几何概型交汇 “In the intersection of knowledge networks at the test questions, the basic knowledge of mathematics test to achieve the necessary requirements. ” This is an important idea of ​​college entrance examination proposition. As an integral part of senior high school new curriculum, its important application One is to find the trapezoidal area, and most of the college entrance examination in the fixed points and other mathematical knowledge interchange test system. Here is a breakdown as follows. First, the integration of fixed points and geometry
