The force F (in newtons) of a hydraulic cylinder in a press is proportional to the square of sec x, where x is the distance (in meters) that the cylinder is extended in its cycle. The domain of F is [0, /3], and F(0) = 500. (a) Find F as a function of x. (b) Find the average force exerted by the press over the interval [0, /3]
An automobile's power is proportional to the cube of its speed on a level road in still air. This relationship between speed and engine power for the Gofaster model XP9 is:
