Chapter 4, Problem 40E(choose chapter or problem)
Oblique tracking A ship leaves port traveling southwest at a rate of 12 mi/hr. At noon, the ship reaches its closest approach to a radar station, which is on the shore 1.5 mi from the port. If the ship maintains its speed and course, what is the rate of change of the tracking angle \(\theta\) between the radar station and the ship at 1:30 P.M. (see figure)? (Hint: Use the Law of Sines.)
