$barv = 3cos((5pi)/12)hati + 3sin((5pi)/12)hatj$

let $barv$ be the vector with components $v_xhati + v_yhat j$

$v_x = 3cos((5pi)/12)$

$v_y = 3sin((5pi)/12)$

$barv = 3cos((5pi)/12)hati + 3sin((5pi)/12)hatj$

What are the components of the vector between the origin and the polar coordinate (3, (5pi)/12)(3, (5pi)/12)?
