Let be the line given by the vector equation
.
First, we use the director vectors of the lines L1 and L2 to get the
vector equation of the plane containing them, which we denote by . This is,
We observe that . Therefore, the vector equation of
defines a plane and
is a normal vector to
Finally, the vector equation for the wanted plane, which we denote by , is
Thus, if , then
and since
is parallel to
, then it is perpendicular to
.
