$2\mathrm{.}5$ Vectors$/$Coordinate Transformations

a$.$ For the following line segments, write the vector notation based on the information given and write

the unit vectors for each of the line segments. In MATLAB, define the vectors representing each line

segment using both the $x,y$ lengths and using a unit vector and magnitude variable.

vector $q$ :

vector $u$ :

b$.$ In MATLAB define the unit vectors for $r$ and $s_p.$ and the coordinate transformation matrix. Then

use these to define the position vector for $P.$
