1、必修一编号:编制人:审核人:领导签字:第三章函数与方程1、1、2 第一课时用二分法求方程的近似解班级:小组:姓名:教师评价:学习目标:1、理解二分法的概念及其适用条件,能借助计算器等信息技术工具,运用二分法求方程的近似解。2、让学生在求方程近似解的实例中感知二分法思想,从中体会函数的零点与方程之间的联系,初步形成用函数观点处理问题的能力。3、体会数学逼近过程,感受精确与近似的相对统一;让学生激情投入,积极思考,做学习的主人。重点:学会用二分法求函数零点的近似值。难点:理解用二分法求函数零点的近似值的原理。预习案使用说明、学法指导:1、用 15 分钟左右的时间,阅读探究课本的基础知识,通过自主高
2、效预习,提升自己的阅读理解能力。2、完成教材助读设置的问题,然后结合课本的基础知识和例题,完成预习自测题。3、将预习中不能解决的问题标出来,并写到后面的“我的疑惑”处。.相关知识1、函数零点的定义是怎样的?2、函数2()21f xxx的正零点所在的区间是()A、(1,2)B、(2,3)C、(0,1)D、(3,4)学习建议请同学们回顾这部分旧知识,不使它们成为学习本课时内容的障碍。.教材助读阅读教材,回答下列问题;1、你能说出函数()ln26fxxx的零点大致在哪个区间吗?2、二分法是如何定义的?3、二分法可用来求任意函数的任意零点吗?4、给定精确度,用二分法求函数()f x零点 近似值的步骤如
3、下:(1)确定区间,a b,验证 _,给定精确度;(2)求区间(a,b)的中点c;(3)计算()f c;若()0f c,则 _就是函数的零点;若().()0f af c,则令 b=c(此时零点0 x_);若().()0,f cf b则令 a=c(此时零点0 x_);(4)判断是否达到精确度,即若 _,则得到零点近似值a 或 b;否则重复(2)(4)。5、关于二分法的叙述,正确的是:_.用二分法求函数零点近似值时,可将所得零点所在区间内的任意一值作为函数零点的近似值;只有在求函数零点的近似值时,才用二分法;设单调函数()f x在区间,a b上是连续的,且().()0f af b,用二分法求零点时
4、,取02abx,若0()0f x,则函数()f x零点为0 x。6、(判断)求方程的根的近似值可以转化为函数的零点的近似值。().预习自测学习建议自测题体现一定的基础性,又有一定的思维含量,只有“细心才对,思考才会”。1、图 1 中函数的图像与x 轴均有交点,其中不能用二分法求函数零点的是()2、用二分法求函数3()5f xx的零点,可以取的初始区间最好是()A、2,1B、1,0C、2,1D、0,13、判断方程3310 xx在区间(0,1)内是否有解??我的疑惑 请将预习中不能解决的问题写下来,供课堂解决。探究案.学始于疑我思考、我收获“学始于疑”的内容为同学们进行下面探究学习前首先要思考的启
5、发性问题,这些问题同学们不必作答,学完“探究案”后这些问题就会迎刃而解。1、什么样的函数才可以用二分法求零点呢?2、用二分法求函数的零点时,何时才终止呢?3、如何判断是否达到所要求的精确度?学习建议请用 2 分钟时间认真思考这些问题,并结合预习中自己的疑惑开始下面的探究学习。.质疑探究质疑解疑、合作探究(一)基础知识探究问题 1:如何准确理解“二分法”的含义?文档编码:CS4K7X4D9X5 HW1T5R3N5J10 ZN8Z7H6T4G7文档编码:CS4K7X4D9X5 HW1T5R3N5J10 ZN8Z7H6T4G7文档编码:CS4K7X4D9X5 HW1T5R3N5J10 ZN8Z7H6
