(a)
To find:The set of parametric equations.
(a)
Answer to Problem 18E
Theparametric equations are
Explanation of Solution
Given information:The points are
Formula used: The parametric equations for the line parallel to
Calculation:
The direction vector can be obtained by the given two points as:
So, the normal vector is
Substitute 2 for
Substitute
Substitute 5 for
Therefore, the set of parametric equations are
(b)
To find:The set of symmetric equations for the line passes through the two points
(b)
Answer to Problem 18E
Theset of symmetric equation of line is not possible.
Explanation of Solution
Given information:The points are
Calculation:
The normal vector is
Therefore, the set of symmetric equation of line is not possible.
