$6 cos((3pi)/8)i -6sin((3pi)/8)j$

Corresponding cartesean coordinates would be $6 cos((-3pi)/8), 6 sin ((-3pi)/8)$

Or $6 cos((3pi)/8), -6sin((3pi)/8)$

The vector in component form would be

$6 cos((3pi)/8)i -6sin((3pi)/8)j$

What are the components of the vector between the origin and the polar coordinate (6, (-3pi)/8)(6, (-3pi)/8)?
