在新课标高考中,对三角的考查有逐步强化的趋势,分值也有所增加.突破秘笈:由于三角函数题是基础题、常规题,属于容易题、可做题的范畴,故建议三角函数的复习应控制在课本知识的范围和难度上,这些足够适应未来高考命题的要求.解答有关三角题的一般策略为:(1)发现差异:观察角、函数运算间的差异,即进行所谓的“差异分析”.(2)寻找联系:运用相关三角公式,找出差异之间的内在联系. In the new college entrance examination entrance exam, the triangle of the test has gradually strengthened the trend, the score has also increased. Breakthrough Tips: Since the trigonometric function is the basic questions, regular questions, are easy questions, do the topic category, it is suggested that the triangle The review of the function should be controlled in the scope and difficulty of the textbook knowledge, which is enough to meet the requirements of future college entrance examination questions. Answer The general strategy of the triangle questions: (1) to find differences: observation angle, the difference between the function operation, “Difference Analysis ”. (2) Find the contact: use the relevant trigonometric formula to find the internal relations between the differences.
