1．1．1正弦定理 ●教学目标 知识与技能：通过对任意三角形边长和角度关系的探索，掌握正弦定理的内容及其证明方法； 会运用正弦定理与三角形内角和定理解斜三角形的两类基本问题。 过程与方法：让学生从已有的几何知识出发,共同探究在任意三角形中，边与其对角的关系， 引导学生通过观察，推导，比较，由特殊到一般归纳出正弦定理，并进行定理基本应用的实践操作。 情感态度与价值观：培养学生在方程思想指导下处理解三角形问题的运算能力；培养学生合 情推理探索数学规律的数学思思想能力，通过三角形函数、正弦定理、向量的数量积等知识间的联系来体现事物之间的普遍联系与辩证统一。 ●教学重点 正弦定理的探索和证明及其基本应用。 ●教学难点 已知两边和其中一边的对角解三角形时判断解的个数。 ●教学过程 一.课题导入 如图1．1-1，固定?ABC 的边CB 及∠B ，使边AC 绕着顶点C 转动。 思考：∠C 的大小与它的对边AB 的长度之间有怎样的数量关系？ 显然，边AB 的长度随着其对角∠C 的大小的增大而增大。 能否用一个等式把这种关系精确地表示出来？ 二.讲授新课 [探索研究] 在初中，我们已学过如何解直角三角形，下面就首先来探讨直角三角形中，角与边的等式关系。如图，在Rt ?ABC 中，设BC=a,AC=b,AB=c, 根据锐角三角函数中正弦函数的定义， 有 sin a A c =，sin b B c =，又sin 1c C c ==, 则sin sin sin a b c c A B C === 从而在直角三角形ABC 中，sin sin sin a b c A B C == 思考1：那么对于任意的三角形，以上关系式是否仍然成立？（由学生讨论、分析） 可分为锐角三角形和钝角三角形两种情况： 如图1．1-3，（1）当?ABC 是锐角三角形时，设边AB 上的高是CD ，根据任意角三角函数的定义， 有CD=sin sin a B b A =,则sin sin a b A B = ， C 同理可得sin sin c b C B = ， b a 从而 sin sin a b A B = sin c C = A c B （2）当?ABC 是钝角三角形时，以上关系式仍然成立。（由学生课后自己推导） 思考2：还有其方法吗？ 由于涉及边长问题，从而可以考虑用向量来研究这问题。 C A B B C A
UNIT 1 Anne’s best friend 你是不是想有一位无话不谈能推心置腹的朋友呢？或者你是不是担 心你的朋友会嘲笑你，会不理解你目前的困境呢？ 安妮弗兰克想要的是第一种类型的朋友，于是她就把日记当成了她 最好的朋友。安妮在第二次世界大战期间住在荷兰的阿姆斯特丹。她一 家人都是犹太人，所以他们不得不躲藏起来，否则他们就会被德国纳粹 抓去。她和她的家人躲藏了二十五个月之后才被发现。在这段时间里， 她唯一的忠实朋友就是她的日记了。她说，“我不愿像大多数人那样在 日记中记流水账。我要把这本日记当作我的朋友，我要把我这个朋友称 作基蒂”。 安妮从1942年七月起就躲藏在那里了，现在来看看他当时 的心情吧。 1944年6月15日，星期四 亲爱的基蒂： 我不知道这是不是因为我长久无法出门的缘故，我变得对一 切与大自然有关的事物都无比狂热。我记得非常清楚，以前，湛 蓝的天空、鸟儿的歌唱、月光和鲜花，从未令我心迷神往过。自 从我来到这里，这一切都变了。 …比方说，有天晚上天气很暖和，我熬到 11点半故意不睡 觉，为的是独自好好看看月亮。但是因为月光太亮了，我不敢打 开窗户。还有一次，就在五个月以前的一个晚上，我碰巧在楼 上，窗户是开着的。我一直等到非关窗不可的时候才下楼去。漆 黑的夜晚，风吹雨打，雷电交加，我全然被这种力量镇住了。这 是我一年半以来第一次目睹夜晚… 不幸的是……我只能透过那满是灰尘的窗帘下那脏兮兮的窗 户看看大自然。只能隔着窗户看那大自然实在没意思，因为大自 然是需要真正体验的东西。 Using Language 亲爱的王小姐： 现在我同班上的同学有些麻烦事。我跟我们班里的一位男同学一直相处的很好。我们常常一起做家庭作业，而且很乐意互相帮助。我们成了真正好朋友。可是，其他同学却在背后议论起来，他们说我和这位男同学在谈恋爱，这使我很生气。我不想中断这段友谊，但是，我又讨厌人家背后说闲话。我该怎么办呢？

§1.1.1 正弦定理 1. 掌握正弦定理的内容； 2. 掌握正弦定理的证明方法； 3. 会运用正弦定理解斜三角形的两类基本问题． CB 及∠B ，使边AC 绕着 顶点C 转动． 思考：∠C 的大小与它的对边AB 的长度之间有怎样的数量关系？ 显然，边AB 的长度随着其对角∠C 的大小的增大而 ．能否用一个等式把这种关系精确地表示出来？ 二、新课导学 ※ 学习探究 探究1：在初中，我们已学过如何解直角三角形，下面就首先来探讨直角三角形中，角与边的等式关系. 如图，在Rt ?ABC 中，设BC =a ，AC =b ，AB =c ， 根据锐角三角函数中正弦函数的定义， 有sin a A c =，sin b B c =，又sin 1c C c ==， 从而在直角三角形ABC 中，sin sin sin a b c A B C == ． ( 探究2：那么对于任意的三角形，以上关系式是否仍然成立？ 可分为锐角三角形和钝角三角形两种情况： 当?ABC 是锐角三角形时，设边AB 上的高是 CD ，根据任意角三角函数的定义， 有CD =sin sin a B b A =，则sin sin a b A B = ， 同理可得sin sin c b C B = ， 从而sin sin a b A B =sin c C =． 类似可推出，当?ABC 是钝角三角形时，以上关系式仍然成立．请你试试导. 新知：正弦定理 在一个三角形中，各边和它所对角的 的比相等，即 sin sin a b A B = sin c C =． 试试： （1）在ABC ?中，一定成立的等式是（ ） ． A ．sin sin a A b B = B .cos cos a A b B = C . sin sin a B b A = D .cos cos a B b A = （2）已知△ABC 中，a ＝4，b ＝8，∠A ＝30°，则∠B 等于 ． [理解定理] （1）正弦定理说明同一三角形中，边与其对角的正弦成正比，且比例系数为同一正数，即存在正数k 使sin a k A =， ，sin c k C =； （2）sin sin a b A B =sin c C =等价于 ，sin sin c b C B =，sin a A =sin c C ． （3）正弦定理的基本作用为： ①已知三角形的任意两角及其一边可以求其他边，如sin sin b A a B =； b = ． ②已知三角形的任意两边与其中一边的对角可以求其他角的正弦值， 如sin sin a A B b =；sin C = ． （4）一般地，已知三角形的某些边和角，求其它 的边和角的过程叫作解三角形． ※ 典型例题 例1. 在ABC ?中， 已知45A =，60B =，42a =cm ，解三角形．
