1)understand the significance of all the symbols used when the
equation of a straight line is expressed in the form r = a + tb;
2)determine whether two lines are parallel, intersect or are skew;
3)find the angle between two lines, and the point of intersection of two lines when it exists;

equation of a plane is expressed in either of the forms ax + by + cz = d or (r ?a).n = 0 ;
5)use equations of lines and planes to solve problems concerning
distances, angles and intersections, and in particular:
