Components are $6.988$ and $0.416$

The components of the vector between the origin and the polar coordinate $(r,theta)$ are given by $rcostheta$ and $rsintheta$ .

Given the polar coordinates $(7,(13pi)/12)$ , components in the instant case will be

$7xxcos(13pi)/12=6.988$

and $7xxsin(13pi)/12=0.416$

What are the components of the vector between the origin and the polar coordinate (7, (13pi)/12)(7, (13pi)/12)?
