空间直线的向量表示及其在求点到空间直线距离的应用

Vectors expression of spatial line and its applications of solving the distance from point to spatial line

根据空间直线一般方程的基本特点,利用线性方程组的基本理论,给出了空间直线的向量表示,并结合向量正交的几何意义和一元函数极值的基本求法,给出了两种求点到空间直线距离的简单方法.

Using the basic characteristic of spatial line＇ s ecumenical equation and the basic theorem of a system of linear equation, the vector expression of spatial line was given. Using the vectors expression of spatial line and combine the geometric explanation of vector orthogonal or the method of the function of one variable, two simple methods of solving the distance from a point to a spatial line were presented.
