正弦、余弦定理反映了三角形边、角间的关系,体现了数与形的结合,且易与三角函数的图像与性质、简单的三角恒等变换、平面向量等知识点相联系,符合高考命题“要在知识点的交汇处命题”的要求,故“解三角形”问题一直是历年高考热点之一.下面我们结合2012年高考真题对“解三角形”试题的 Sine and cosine theorem reflect the relationship between the edges and corners of triangles, which embodies the combination of numbers and shapes. It is easily connected with the knowledge and features of trigonometric functions, simple trigonometric transforms and plane vectors, “The triangle” question has been one of the hot spots in the college entrance examination over the years. Here we combine the 2012 college entrance examination Zhenti “” solution to the triangle "test questions
