作为现代数学的重要标志之一的向量已进入了中学数学,为用代数方法研究几何问题提供了强有力的工具,促进了高中几何的代数化.在高中数学体系中,几何占有很重要的地位.有些几何问题用常规方法解决往往比较复杂,运用向量做行与数的转化,则使会过程得到大大简化.向量法应用于平面几何中时,能将平面几何中的一些问题代数化、程序化,从而有效解决,体现了数学中数与形的完美结合.
As one of the most important symbols of modern mathematics, the vector has entered the middle school mathematics, which provides a powerful tool for studying the geometric problems by algebraic method and promotes the algebraic geometry of high school. Geometry occupies a very important position in the high school mathematics system Some geometric problems are often complicated to solve by conventional methods, and the use of vector to do the conversion of rows and numbers greatly simplifies the process. When vector method is applied to plane geometry, some problems in plane geometry can be algebraic. In order to effectively solve the problem, it embodies the perfect combination of numbers and shapes in mathematics.
