坐标法又称解析法,是解析几何中最基本的方法.其思路是:通过建立平面直角坐标系,把几何问题转化为代数问题,从而利用代数知识使问题得以解决.同学们在解决一些与向量有关的问题时若适当考虑坐标法,可使向量的运算完全代数化,将数与形紧密地结合起来,使得用向量的方 Coordinate method, also known as analytic method, is the most basic method of analytic geometry.The idea is: through the establishment of planar rectangular coordinate system, the geometric problems into algebraic problems, so that the use of algebraic knowledge to solve the problem.Students in solving some of the Vector-related issues, if properly considered coordinate method, the vector operations can be fully algebraic, the number and shape closely together, making use of the square of the vector
