纵观近三年高考试题和高考模拟试题,不难发现,解析法在解题中的广泛应用.所谓解析法就是通过建立坐标系,把点和坐标、曲线和方程联系起来,从而将解析几何知识迁移到代数、三角和实际应用当中,帮助我们更好地解决问题,这就更加丰富了数形结合思想,使解题起到事半功倍的效果. Throughout the past three years college entrance examination exam questions and college entrance examination simulation test, it is not difficult to find that the analytical method is widely used in solving problems.The so-called analytical method is through the establishment of coordinate system, the point and coordinates, curves and equations, which will be analytic geometry The transfer of knowledge to algebra, trigonometry and practical applications helps us solve problems better, which further enriches the effect of combining figures with form and thinking, and solving problems more efficiently.
