Section Content

At the end of this section, students should be able to:

• express a vector in the form $$\begin{pmatrix} x\\y \\z \end{pmatrix}$$ or $$xi+yj+zk$$ where $$i, j$$ and $$k$$ are unit vectors in the direction of $$x-, y-$$ and $$z-$$ axis respectively;
• define equality of two vectors;
• find the equation of the plane, in the form $$xi+yj+zk=d$$, $$r.n=d$$, given a point in the plane and the normal to the plane.
