$¯ ¯ ¯ V = - 8 cos (\frac{5 π}{8}) ˆ i + - 8 sin (\frac{5 π}{8}) ˆ j$ $barV = -8cos((5pi)/8)hati + -8sin((5pi)/8)hatj$

$¯ ¯ ¯ V = - 8 cos (\frac{5 π}{8}) ˆ i + - 8 sin (\frac{5 π}{8}) ˆ j$ $barV = -8cos((5pi)/8)hati + -8sin((5pi)/8)hatj$

What are the components of the vector between the origin and the polar coordinate (-8, (5pi)/8)(−8,5π8)(-8, (5pi)/8)?
