作为集数与形于一体的特殊的数学量,向量的运算方式具有自身的独特性,特别是其运算的几何特性,为我们解决平面向量问题提供了广阔的思维发展空间.本文笔者拟借助向量运算的几何意义来赏析教学实践中遇到的涉及平面向量的新颖综合问题,供读者参考.1.基于线性运算几何意义求解向量的线性运算中的加法遵循的平行四边形法则和三角形法则、减法遵循的三角形法则、数乘运算
As a special mathematical quantity that integrates set number and shape, vector computing has its own uniqueness, especially the geometrical characteristics of its operation, which provides a vast space of thinking for us to solve the problem of plane vector.In this paper, The Geometrical Significance of Computation Appreciates the New Synthesis Problem Involving Plane Vector Encountered in Teaching Practice for Reference I. Reciprocal Parallelogram and Triangle Rule Addition in Linear Operation Based on Geometric Calculation of Linear Computation Meaning and Subtraction Follow Triangle rule, the number of operations
