A vector v in a plane is a line segment with a specified direction, where the component form is given by two coordinates (a,b) .

Question
A vector v in a plane is a line segment with a specified direction, where the component form is given by
two coordinates (a,b) . Similarly, we may define a vector w in three-dimensional space as a line
segment in space with a specified direction where the component form is given by three coordinates (a,
b, c) .
For example, a vector w from the origin to a point P (2, 3, 3) is given in component form as w = (2, 3,
3) or, in terms of the unit vectors i = (1, 0, 0) , j= <0, 1, 0o> , and k = (0, 0, 1> , as w = 2i + 3j + 3k.
Use this convention for Exercises 99–100.
