俗话说,居安思危,思则有备,有备无患。高中教师要准备好教案,这是老师职责的一部分。教案可以让上课时的教学氛围非常活跃,帮助高中教师缓解教学的压力,提高教学质量。那么,你知道高中教案要怎么写呢?下面是小编帮大家编辑的《高考英语单元知识考点Unit9 Technology 科技导学案》,相信能对大家有所帮助。
高考英语顶尖学案:大纲版一名优秀的教师在教学方面无论做什么事都有计划和准备,作为教师就要在上课前做好适合自己的教案。教案可以让学生们能够在上课时充分理解所教内容,让教师能够快速的解决各种教学问题。那么如何写好我们的教案呢?以下是小编为大家收集的“对数(1)教案苏教版必修1”欢迎大家阅读,希望对大家有所帮助。
3.2.1对数(1)
教学目标:
1.理解对数的概念;
2.能够进行对数式与指数式的互化;
3.会根据对数的概念求一些特殊的对数式的值.
教学重点:
对数的概念,对数式与指数式的相互转化,并求一些特殊的对数式的值;
教学难点:
对数概念的引入与理解.
教学过程:
一、情境创设
假设2005年我国的国民生产总值为a亿元,如每年平均增长8%,那么经过多少年,国民生产总值是2005年的2倍?
根据题目列出方程:______________________.
提问:此方程的特征是什么?已知底数和幂,求指数!
情境问题:已知底数和指数求幂,通常用乘方运算;而已知指数和幂,则通常用开方运算或分数指数幂运算,已知底数和幂,如何求指数呢?
二、数学建构
1.对数的定义.
一般地,如果a(a>0,a≠1)的b次幂等于N,即ab=N,那么就称b是以a为底N的对数,记作logaN,即b=logaN.
其中,a叫作对数的底数,N叫做对数的真数.
2.对数的性质:
(1)真数N>0,零和负数没有对数;
(2)loga1=0(a>0,a≠1);
(3)logaa=1(a>0,a≠1);
(4)a=N(a>0,a≠1).
3.两个重要对数:
(1)常用对数(commonlogarithm):以10为底的对数lgN.
(2)自然对数(naturallogarithm):以无理数为底的对数lnN.
三、数学应用
例1将下列指数式改写成对数式.
(1)24=16;(2);(3);(4).
例2求下列各式的值.
(1)log264;(2)log832.
基础练习:
log10100=;log255=;
log2=;log4=;
log33=;logaa=;
log31=;loga1=.
例3将下列对数式改写成指数式
(1)log5125=3;(2)log3=-2;(3)lga=-1.699.
例4已知loga2=m,loga3=n,求a2mn的值.
练习:
1.(1)lg(lg10)=;(2)lg(lne)=;
(3)log6[log4(log381)]=;(4)log3=1,则x=________.
2.把logx=z改写成指数式是.
3.求2的值.
4.设,则满足的x值为_______.
5.设x=log23,求.
四、小结
1.对数的定义:b=logaNab=N.
2.对数的运算:用指数运算进行对数运算.
3.对数恒等式.
4.对数的意义:对数表示一种运算,也表示一种结果.
五、作业
课本P79习题3.2(1)1,2,3(1)~(4).
