| Abstract: | 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. |
