三角函数解答题是历年高考必考内容之一,成为6道解答题中的第一题,难度一般比较小。三角函数中,以公式多而著称。解题方法也较灵活,但并不是无章可寻。解题套路重要,解题的思维方式更重要。只有掌握了思维方式,解题套路才能用得正确、巧妙。接下来我们一起欣赏今年的几道有代表性的高考函数大题。例1(江西卷理17)在△ABC中,角A,B,C的对边分
Triangular function answer questions over the years will be one of the college entrance examination content to become the first six questions answer questions, the difficulty is generally relatively small. Trigonometric functions are well known for their formulas. Problem-solving methods are more flexible, but not absent-minded. Problem solving routines important solution to the problem of thinking is more important. Only mastered the way of thinking, problem-solving routines can be used correctly, ingenious. Next, we appreciate this year’s several representative of the college entrance examination function big problem. Example 1 (Jiangxi Volume 17) △ ABC in the corner A, B, C on the edge of the points
