$barV = -7sqrt(3)/2hati -7/2hatj$

$barV = -7cos((-11pi)/6)hati + -7sin((-11pi)/6)hatj$

$barV = -7sqrt(3)/2hati + -7/2hatj$

$barV = -7sqrt(3)/2hati -7/2hatj$

$barV = -7cos((-11pi)/6)hati + -7sin((-11pi)/6)hatj$

$barV = -7sqrt(3)/2hati + -7/2hatj$

What are the components of the vector between the origin and the polar coordinate (-7, (-11pi)/6)(-7, (-11pi)/6)?
