Chapter 9 Vectors
vector equation of a
straight line
r at Xb
where is vector and to the
a a position parallel
vector b
Cartesian form is x
g ggaz 2593
each of these expressions is equal to x
where bby is a direction vector and
g is
positio
vector
The vector
equation of a plane is
r at Xb thee
where a is position vector in the plane
non
b and c are parallel non zero vectors
Cartesian equation is ax
by to 2 d
where is the normal vector to the plane
g
Point are collinear if
they all lie on the same
line
straight
Normal vector is a vector that is perpendicular
to the
plane
Points are coplanar if they all lie on the same plane
