Question

A boat sails directly toward a 150-meter skyscraper that stands on the edge of a harbor. The angular size u of the building is the angle formed by lines from the top and bottom of the building to the observer (as shown).

a. What is the rate of change of the angular size du>dx when the boat is x = 500 m from the building?

b. Graph du>dx as a function of x and determine the point at which the angular size changes most rapidly.
