Chapter 6, Problem 43(choose chapter or problem)
The latitude of a point P on the surface of the Earth is specified by means of the angle u in the figure. For instance, the latitude of Paris, France, is 4852 N. The letter N is used here to indicate that the location is north of, rather than south of, the equator. (Recall that the notation 52 indicates 52/60 of one degree.) In Exercises 43 48, use the arc length formula (and your calculator) to determine the distance from the given location P to the equator. Assume that the Earth is a sphere with radius OP OE 3960 miles. Round each answer to the nearest 10 miles.
