Description

This activity book answers the fundamental question, "How can the distance between any two locations on our planet be calculated by using the geographic coordinates of each location." As an added benefit, the reader also learns the names of capitals of countries on every continent as they calculate distances between two capital cities within the same continent. There are 18 examples as well as 98 exercise problems with complete step-by-step solutions. To aid the visual learner, each of the examples and solutions include an accompanying illustration of a spherical triangle. The word "Approximating" is used in the title since the Earth is not a perfect sphere but is approximately spherical with an average radius of 3959 miles.
