Question

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

Answer 1

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

Explanation:

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`
