专题五用锐角三角函数解航海问题航海问题主要包括求航行的时间、求航行速度、判断是否有触礁危险等,是考试中的热点问题.解决航行问题的关键是从实际问题中构建一个或两个直角三角形,通过三角函数直接解决或根据图形中的数量关系建立方程解决.例1如图1,灯塔A周围1 000米水域内有礁石,一舰艇由西向东航行,在O处测得灯塔A在北偏东74°方向线上,这时O,A相距4 200米,如果不改变航向,此舰艇是否有触礁的危险?分析:要判断舰艇是否有触礁的危险,关键比较点A到正东方向的距离与1 000米的大小,因此,需过点A向正东方向引垂线,转化为直角三角形中的问题.解:如图1,过点A作AB与正东方向线垂直,垂足为B.在Rt△AOB中,OA=4 200,∠AOB=90°-74°=16°.AB=AO·sin∠AOB=4 200·sin16°=4 200×0.275 6≈1 158(米).因为1 158>1 000,所以此舰艇按原航向继续航行没有触礁的危险.说明:本题是一道比较简单的航行问题,不仅要能从实际问题中构造出直角三角形,而且还要注意一些解题技巧,如能用乘法的运算的,不用除法,能用正弦计算的,不用余弦.例2如图2,某船以每小时36海里的速度向正东方向航行,在点A测得某岛C在北偏东60°方向上,航行半小时后到达点B,测得该岛在北偏东30°方向上,已知该岛周围16海里内有暗礁.(1)试说明点B是否在暗礁区域外?(2)若继续向东航行有无触礁危险?请说明理由.分析:要判断点B是否在暗礁区域外.则需要计算BC的长度,看其长度是否大于16海里,若BC>16海里,则点B在暗礁区域外;要判断继续向东航行有无触礁危险,则需要计算船到岛C的最短距离,看是否小于16海里.若小于16海里,则有触礁的危险.为此,需要构造直角三角形解决.解:(1)过点B 作BD ∥A E ,交AC 于点D .因为AB =36×0.5=18(海里),∠ADB =60°,∠DBC =30°,所以∠ACB =30°.又∠CAB =30°,所以BC =AB .即BC =AB =18>16.所以点B 在暗礁区域外.(2)过点C 作CH ⊥AB ,垂足为H ,在Rt △CHB 中,∠BCH =30°,令BH =x ,则CH .在Rt △ACH 中,∠CAH =30°,所以3tan 30CH AH x ====o . 因为AH AB BH =+,所以318x x =+.解得9x =.所以16CH =<.所以船继续向东航行有触礁的危险.说明:有无触礁问题是航海中的热点,也是中考试题中经常出现的试题.解决此类问题需要正确理解题意,从实际问题构建直角三角形模型.专题训练:1.如图3,一艘船向正东方向航行,在B 处测得有一灯塔在它的北偏东30°,距离为72海里的A 处.当行至C 处测得灯塔恰好在它的正北方向,求此时它与灯塔的距离AC (计算结果精确到0.1海里).2.如图4,海上有一灯塔P ,在它周围3海里处有暗礁.一艘客轮以9海里/时的速度由西向东航行,行至A 点处测得P 在它的北偏东60°的方向,继续行驶20分钟后,到达B 处又测得灯塔P 在它的北偏东45°方向. 问客轮不改变方向继续前进有无触礁的危险?参考答案:1.据题意∠ABC =90°-30°=60°,AB =72.在Rt △ABC 中,因为sin ∠ABC =AC AB, 所以AC =AB sin ∠ABC =72sin60°=72×1.7322≈62.4(海里). 2.过P 作PC ⊥AB 于C 点.据题意知:AB =9×26=3,∠P AB =90°-60°=30°,∠PBC =90°-45°=45°,∠PCB =90°. 所以PC =BC .在Rt △P AC 中,tan 303PC PC PC AC AB BC PC===++o .3PC PC =+.所以3PC =>. 所以客轮不改变方向继续前进无触礁危险.。

11月6日,三位女红军住进农民徐解秀家里,当天晚上四人睡在一起,盖的是她床上的一块烂棉絮和红军的一条被子。
第二天临走时,为感谢徐解秀,女红军把她们仅有的一条被子剪了一半送给她。
徐解秀后来回忆说:“虽然那时候为了红军留下的半条被子吃了点儿苦,不过也让我明白了一个道理,什么叫红军?什么叫共产党?共产党就是自己只有一条被子,也要给穷苦人半条的人。
