3.3.22 Line and plane in space
condition: Find the distance between two lines: \[ \begin{array}{l} \frac{x+7}{1}=\frac{y+4}{14}=\frac{z+3}{-2} \\ \frac{x-21}{6}=\frac{y+5}{-4}=\frac{z-2}{-1} \end{array} \]
Straight lines and planes in space. Intersection of lines and planes, calculation of the distance of a line and a plane, angles between lines and planes, finding equations of lines and planes in space, and much more.
