(1 point) A curve in polar coordinates is given by: r = 7 + 2 costheta.
Point P is at theta = {16 pi}/ {14}.

a.) Find polar coordinate r for P, with r > 0 and pi r =

b.) Find cartesian coordinates for point P.
x =

y =

c.) How may times does the curve pass through the origin when 0 \lt \theta \lt 2 \pi ?
