摘要
用高中向量基础知识和待定法可非常方便地得出n(n≥3)维线性空间中异面直线的公垂线方程.若在大学数学教学中挖掘与中学数学的衔接和联系,则可在很大程度上降低大学数学的教学难度.
By using basic knowledge of vector and the method of undetermined coeffient in high school mathematics, the equation of common vertical line of two lines in different planes can be solved very easily. By excavating the teaching convergence between middle school mathematics and college mathematics, the teaching difficulty is largely reduced.
