Step 1:

\

$\"\"$

\

The croos product $\"\"$ is orthogonal to both $\"\"$ and $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Step 2:

\

$\"\"$

\

Formula for the unit vector $\"\"$

\

The unit vector $\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

The second unit vector orthoganal to both $\"\"$ and $\"\"$ $\"\"$

\

(This is negative of the previous vector).

\

The unit vectors are $\"\"$ and $\"\"$ .

\

Solution:

\

The unit vectors are $\"\"$ and $\"\"$ .
