A road is shaped in the shape of the cardoid r=1000(1+cos(theta)) (polar coordinate form of the curve), where r is in meters. When a car is traveling on the road at the point represented by theta = Pi/6, the car is traveling at a speed of 30 meters per second. Determine dtheta/dt. The car is traveling counter-clockwise along the road.
