在初中数学中,解直角三角形的应用问题一直是非常重要的内容.在生活中解决实际问题时,解直角三角形有着广泛的应用.因此,从2014年开始,我省的数学中考第22题改为考查“解直角三角形”的题型,特别是锐角三角函数与实际问题相结合的题目.建筑物的高度与水平距离、船只航行的时间与速度、船只是否有触礁危险、船只能否及时到达、水库大坝坡度等等是海南数学中考22题的命题热点.解答这类问题主要是把实际问题转化为解直角三
In junior high school mathematics, solving the application of right triangle has always been a very important issue.In the life to solve practical problems, the right angle triangle has a wide range of applications.Therefore, from 2014 onwards, In order to examine the type of “right-angled triangle”, especially the combination of acute trigonometric functions and practical problems, the height and horizontal distance of buildings, the time and speed of sailing vessels, Timely arrival, dam slope and so on are the hot topics in the Hainan mathematics test 22. The answer to these problems is mainly to transform the actual problem into a right angle three
