Hey. Here is the question:
[tex]
\underline{b}= -8\underline{i} - 6\underline{j}
[/tex]
I need to find a unit vector perpendicular to vector b.
Ive come up with the following:
[tex]
10 \times |\underline{x}| \cos 90 = \underline{b} \bullet \underline{x}
[/tex]
I don't know if what I've done is even close to what i need to do, but from there, I am completely stuck.
Any help greatly appreciated.
Dan.
