在2014年高考全国18套试卷中,只有全国新课标卷没考三角函数解答题,其他的17套试题中有11套三角函数解答题都与三角形有关,足见以三角形为背景考查三角函数知识点的重要性.本文以2014年各地高考题为例,总结破解三角形中的三角函数解答题的七招.一、以诱导公式为载体,求三角形的有关参数例1(山东卷)△ABC中,角A,B,C所对的边 Among the 18 sets of national college entrance examination papers in 2014, only the new national curriculum did not test trigonometric function test questions. Among the other 17 sets of questions, 11 sets of trigonometric function solution questions are all related to triangles, which can be used to examine trigonometric knowledge based on triangles The importance of the point.This article takes college entrance examination in 2014 as an example to summarize the seven strokes to solve the trigonometric function answer questions in the triangle.First, take the induction formula as the carrier, find the triangle related parameter example 1 (Shandong volume) △ ABC , Angle A, B, C opposite side
