三角函数解答题一般是高考数学试卷中的第一道解答题,试题难度一般不大,但对全卷的得分影响较大,所以稳拿该题的12分对广大考生至关重要.分析近年高考试卷,可以发现,三角函数解答题涉及三角函数的图象、性质、最值、求值、三角恒等变换及综合应用等问题,常与平面向量,正、余弦定理等各方面知识综合在 Trigonometric function problem is generally the first question in the college entrance examination papers, the difficulty of the questions is generally not large, but the score of the whole volume has a greater impact, so the steady take the question of 12 points for the majority of candidates is crucial. Examination papers, you can find the trigonometric function answer questions related to trigonometric functions of the image, the nature, the most value, evaluation, triangular equal transformation and comprehensive application of such issues, often with planar vector, positive, cosine theorem and other aspects of knowledge synthesis
