Please check my work for: The minute hand of a steeple clock is 4 feet long, and the hour hand is 3 feet long. How fast is the distance between the tips of the hands changing at 3 o'clock. (Hint says to use the law of cosines to computer the distance between the tips of the hands. Also, I determined that the relative rates of change of the angle between the two hands is -11(pi)/6 at 3 o'clock.
