Let S Be a Circular Cylinder of Radius 0 $\vec { u }$

Essay

Let S be a circular cylinder of radius 0.2, such that the center of one end is at the origin and the center of the other end is at the point (4, 0, 7).
Find two unit vectors $\vec { u }$ and $\vec { v }$ in the plane, P, containing the base of the cylinder (i.e., the plane through the origin perpendicular to the axis of the cylinder)which are perpendicular to each other.
