三角函数与解三角形知识复习测试题2015

Do the following three main points: 1 find out the weak. Review process is to sum up the knowledge on the one hand, make the knowledge more coherent system and regularity, but also let the students themselves, looks up the deficiencies. So, we teachers to understand the students knowledge of the situation prior to the review, students not only found widespread deficiencies, but also some shortcomings, for these well designed programs, reasonable arrangement of time, this review is more targeted and more effective. For example, you can design a form for investigation, understanding students weaknesses in each knowledge, put it as a review of key, combined with the problem of textbooks to review, both to avoid casting a net tihaizhanshu, and improve the efficiency of review. 2, good collation. Through six years of study, students in the basics, reading method, exercises, and so already have a certain degree of accumulation, the review stage, teachers should know how to guide the students to label the accumulation, process, form a system of knowledge networks. Exercises for students to be representative, fine, complete, to live, and earnestly do a problem learning a method, class of pass was to get time efficient review results. 3, pay attention to use. The accumulation of knowledge is ultimately to use, therefore, review the situation and life situation to be created in a variety of languages, guide students on the basis of the previous accumulation of knowledge to use to the maximum, and really apply what they have learned. Second, review the content and strategy of the first part: the basics (a) 1, review the main points of Hanyu Pinyin is able to recite and write down the alphabet of Hanyu Pinyin; accurate spelling pronunciation (after reading cacuminal, nasal sound, light, and retroflex sounds), the correct write consonants, vowels and syllables. 2,. main types according to the order of the alphabet of Hanyu Pinyin alphabetical order; fill in the appropriate uppercase and lowercase letters; see phonetic writing words; pinyin to write sentences with dot to select the correct pronunciation of the word; to bring some initial consonants or vowels, word selection. Second, the main types of words (1) Ruby written words; (2) to bring Word to select the correct pronunciation; (3) use a sequencer and radical character lookup method三角函数与解三角形知识复习测试题姓名_学号_班级_(满分150分，时间120分钟)一选择题（每题5分，共50分.请将准确的答案填在答题卡内）1. 已知角的终边经过点，则（ ）A B C D2若，则A.
