向量点乘(内积)和叉乘(外积、向量积)概念及几何意义解读(完整资料).doc

【最新整理,下载后即可编辑】 概念 向量是由n个实数组成的一个n行1列(n*1)或一个1行n列(1*n)的有序数组; 向量的点乘,也叫向量的内积、数量积,对两个向量执行点乘运算,就是对这两个向量对应位一一相乘之后求和的操作,点乘的结果是一个标量。 点乘公式 对于向量a和向量b: a和b的点积公式为: 要求一维向量a和向量b的行列数相同。 点乘几何意义 点乘的几何意义是可以用来表征或计算两个向量之间的夹角,以及在b向量在a向量方向上的投影,有公式: 推导过程如下,首先看一下向量组成:

定义向量: 根据三角形余弦定理有: 根据关系c=a-b(a、b、c均为向量)有: 即: 向量a,b的长度都是可以计算的已知量,从而有a和b间的夹角θ: 根据这个公式就可以计算向量a和向量b之间的夹角。从而就可以进一步判断这两个向量是否是同一方向,是否正交(也就是垂直)等方向关系,具体对应关系为: a·b>0 方向基本相同,夹角在0°到90°之间 a·b=0 正交,相互垂直

a·b<0 方向基本相反,夹角在90°到180°之间 叉乘公式 两个向量的叉乘,又叫向量积、外积、叉积,叉乘的运算结果是一个向量而不是一个标量。并且两个向量的叉积与这两个向量组成的坐标平面垂直。 对于向量a和向量b: a和b的叉乘公式为: 其中: 根据i、j、k间关系,有: 叉乘几何意义 在三维几何中,向量a和向量b的叉乘结果是一个向量,更为熟知的叫法是法向量,该向量垂直于a和b向量构成的平面。 在3D图像学中,叉乘的概念非常有用,可以通过两个向量的叉乘,生成第三个垂直于a,b的法向量,从而构建X、Y、Z坐标系。如下图所示:

数量积与向量积

数量积与向量积 一、两向量的数量积 1、数量积的物理背景:设一物体在常力F 作用下沿直线从点M 1移动到点M 2.以s 表示位移→ 21M M .由物理学知道,力F 所作的功为 W = |F | |s | cos q , 其中q 为F 与s 的夹角. 2、数量积:对于两个向量a 和b ,它们的模|a |、|b |及它们的夹角q 的 余弦的乘积称为向量a 和b 的数量积,记作a ×b ,即 a · b =|a | |b | cos q . 3、数量积与投影: 由于|b | cos q =|b |cos(a ,^ b ),当a 10时,|b | cos(a ,^ b )是向量 b 在向量a 的方向上的投影,于是a ·b =|a | Prj a b . 同理,当b 10时,a·b = |b | Prj b a . 4、数量积的性质: (1) a·a =|a | 2. (2) 对于两个非零向量 a 、b ,如果 a·b =0,则 a ^b ; 反之,如果a ^b ,则a·b =0. 如果认为零向量与任何向量都垂直,则a ^b ?a ·b =0. 5、数量积的运算律: (1)交换律: a·b = b·a ; (2)分配律:(a +b )×c =a ×c +b ×c . (3)(l a )·b = a·(l b )= l(a·b ), (l a )·(m b )= lm(a·b ),l 、m 为数. 例1 试用向量证明三角形的余弦定理. 6、数量积的坐标表示: 设a =(a x , a y , a z ),b =(b x , b y , b z ), 则a·b =a x b x +a y b y +a z b z . 7、两向量夹角的余弦的坐标表示: 设q =(a , ^ b ), 则当a 10、b 10时,有 222222||||cos z y x z y x z z y y x x b b b a a a b a b a b a ++++++=?=b a b a θ. 例2 已知三点M (1,1,1)、A (2,2,1)和B (2,1,2),求DAMB . 解 从M 到A 的向量记为a , 从M 到B 的向量记为b , 则DAMB 就是向量a 与b 的夹角. a ={1,1,0},b ={1,0,1}. 因为 a × b =1′1+1′0+0′1=1, 2011||222=++=a , 2101||222=++=b .

《典范英语》(4a-L5)教学设计

盛年不重来,一日难再晨。及时宜自勉,岁月不待人。 《典范英语》(4a-L5)教学参考 Everyone Got Wet 教学参考的目的在于为实验课提供一个基本的思路和框架,帮助实验教师更好地把握课题理念。课题组鼓励实验教师结合学生的实际情况适当做出调整,将实验课上出特色。 一、教学目标 1.语言能力目标:学生能够听懂故事;能够惟妙惟肖地模仿录音;能够绘声绘色地独立朗读故事;能够理解故事情节;能根据提示复述主要故事情节;巩固字母组合“ck”的拼读规律;能简单地改写故事结局。 2.非语言能力目标:让学生了解“集雨桶”的用途,培养学生的节水意识;感受Kipper 一家人在日常生活中的小乐趣。 二、课时安排 要求每周不少于两课时,每周至少完成一个故事。 三、教师要求 1.教师课前须熟读故事,了解故事内容。 2.对于较难的单词,教师可板书,并配合动作和表情帮助学生理解。 3.全英文授课。 四、教学用具 多媒体设备、CD机、课件(课题组提供)。 五、课堂教学基本步骤 1. 导入(Lead-in):讨论故事标题,猜测故事内容

通过展示图片回顾已学故事情节,引出故事主题,为看图讲故事做好铺垫。 (1)教师利用PPT展示几幅已学故事图片,与学生互动: Look at this picture.(展示1a-L8最后一幅图) Do you remember the story? Who got wet in the story? How did they get wet? Look at this picture. (展示1a-L20第二幅图) Do you remember the story? Who got wet in the story? How did they get wet? (2)展示本课故事标题,自然过渡到讲故事环节:Today, we are going to learn a similar story. Everyone got wet in the story. How did they get wet? Did they fall into the river? Did they have a water fight? Let’s have a look. 2. 看图讲故事(Storytelling):理解故事情节,感受Kipper一家人日常生活中的小乐趣 教师利用课件逐幅播放故事图片,并用丰富的表情、生动的英文和适当的肢体语言给学生绘声绘色地讲故事,让学生感受Kipper一家人日常生活中的小乐趣。 (Picture 1)It was a sunny day. The family were in the yard. Look. What is it? (指向图中的集雨桶) It is a water butt. What was wrong with the water butt? (BQ: Was it leaking?) The water butt was leaking.(指向漏水处) “Oh, I have to mend it,” thought Dad. (Picture 2)Mum looked at the hose.(指向水龙带) What was wrong with the hose? The hose was leaking too.(指向图中漏水处) “Oh bother!” said Mum.(模仿妈妈的动作) Would Mum mend the hose? (Picture 3)Dad mended the water butt. He put a patch on it.(指向集雨桶上的补丁) Was it an easy job to mend the water butt? No. “What a tricky job!” said Dad. (Picture 4)Dad finished. But the water butt burst. All the water came out. Dad got wet.(指向Dad) (Picture 5)Now let’s look at Mum. What did Mum do? Mum mended the hose. Chip helped.(指向Chip) Mum put a patch on it.(指向水龙带上的补丁) “What a tricky job!” said Mum. (Picture 6)Mum put the hose on the tap. She turned on the tap. But the top of the tap came off.(指向图中飞散的水龙头) Oh, no! Mum got very wet. (Picture 7)Dad got a new water butt. He put it on the bricks. Look. What did Dad do? Dad got the hose. He filled up the water butt.(指向Dad)
