4. A rectangular swimming pool is 5 feet deep at one end and 10 feet deep at the other end, and the bottom is an inclined plane. The length and the width of the pool are respectively 40 ft and 20 ft. If the pool is full of water, what is the fluid force on the vertical wall of the pool along a length of the pool? Assume the deep end is along a width of the pool and the weight density of water is 62.4 1bs per ft3. 5. Use integration by parts to find the integral [ e* arctanedx6.
