Chapter 7, Problem 61(choose chapter or problem)
A rotating beacon is located at point P, 5 yardsfrom a wall. The distance d, as measured alongthe wall, where the light shines is given bywhere t is time measured in seconds since thebeacon began to rotate. When the light isaimed at point A. When the beacon is aimed tothe right of A, the distance d is positive, and whenit is aimed to the left of A, the value of d isnegative.Graph the function and estimate the value of d forthe following times.a. b.c. d.e. Determine the position of the beacon whenand discuss the corresponding valueof d for that value of t.
