Hey. Here is the question:(adsbygoogle = window.adsbygoogle || []).push({});

[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 dont know if what ive done is even close to what i need to do, but from there, im completely stuck.

Any help greatly appreciated.

Dan.
