Explanation Given info: θ : Angle of indignation between unit tangent vector T ^ and the x − axis r → ( s ) Is are length parameterization θ = θ ( S ) Be the angle of inclination at r ( s ) Formula used: From the figure unit tangent vector can be written as T ^ = cos θ i ^ + sin θ j ^ = 〈 cos θ , sin θ 〉 θ is function of S So it can be rewrite as T ^ = 〈 cos θ ( s ) , sin θ ( s ) 〉 d T ∧ d s = d d s 〈 cos θ ( s ) , sin θ ( s ) 〉 Differentiation is distributive d T ∧ d s = 〈 d ( cos θ ( s ) ) d s , d ( sin θ ( s ) ) d s 〉 = 〈 d ( cos θ ( s ) ) d ( θ ( s ) ) × d θ ( s ) d s , d ( sin θ ( s ) ) d ( θ ( s ) ) × d ( Q ( s ) ) d s 〉 (Apply chain rule of differentiation)

Coast Guard Patrol Search Mission The pilot of a Coast Guard patrol aircraft on a search mission had just spotted a disabled fishing trawler and decided to go in for a closer look. Flying in a straight line at a constant altitude of 1000 ft and at a steady speed of 256 ft/s, the aircraft passed directly over the trawler. How fast (in ft/s) was the aircraft receding from the trawler when it was 1400 ft from the trawler? (Round your answer to one decimal places.) 1000 ft 180 × ft/s Need Help? Read It SUBMIT ANSWER
