Components of the vector between origin and polar coordinates $(1,(5pi)/8)$ are $-0.3827$ and $0.9239$ .

Components of the vector between origin and polar coordinates $(r,theta)$ are $rcosheta$ and $rsintheta$ .

Hence components of the vector between origin and polar coordinates $(1,(5pi)/8)$ are

$1xxcos((5pi)/8)$ and $1xxsin((5pi)/8)$ or

$cos((5pi)/8)$ and $sin((5pi)/8)$ or

$-0.3827$ and $0.9239$

What are the components of the vector between the origin and the polar coordinate (1, (5pi)/8)(1, (5pi)/8)?
