Measure distance locating nearest public facilities using Haversine and Euclidean Methods
The application of finding the nearest public facility using 2 methods to measure the distance between 2 points, i.e. the Euclidean Method and the Haversine Formula. Euclidean is a heuristic function obtained based on direct distance without obstacles such as to get the value of the length of a diagonal line on a triangle. Whereas Haversine is an equation that looks for the distance of an arc between two points on longitude and latitude. The results of the calculation of the average distance Euclidean deviations with an average value of data 2.539764, and Haversine 2.536912. This shows that the comparison of the measurements of the distance between Euclidean and Haversine has a difference of 0.002852 or the percentage of the distance between the two methods is 99.89 percent. Of the two methods, which yield values almost by measurements on Google maps is Haversine. For Euclidean, it is used to measure the distance between two points on a flat plane so that the results have differences when compared to the Haversine formula.

The Research Triangle
Over the past three decades, the economy of North Carolina's Research Triangle-defined by the cities of Raleigh, Durham, and Chapel Hill-has been transformed from one dependent on agriculture and textiles to one driven by knowledge-based jobs in technology, telecommunications, and pharmaceuticals. Now home to roughly 1.7 million people, the Research Triangle has attracted an influx of new residents from across the country and around the world while continuing to win praise for its high quality of life. At the region's center is the 7,000-acre Research Triangle Park, one of the nation's largest and most prominent research and development campuses. Founded in 1959 through a partnership of local governments, universities, and business leaders, Research Triangle Park has catalyzed the region's rapid growth and hastened its coalescence into a single metropolitan area.
The Research Triangle: From Tobacco Road to Global Prominencedescribes the history, current challenges, and future prospects of this fascinating metropolitan area. Focusing on the personalities and perspectives of key actors in the development of the region, William M. Rohe traces the emergence of the Research Triangle Park and its role in the region's economic transformation. He also addresses some of the downsides of development, illustrating the strains that explosive population growth has placed on the region's school systems, natural resources, transportation infrastructure, and social cohesion. As Rohe shows, the Research Triangle is not a city in the traditional sense but a sprawling conurbation whose rapid, low-density growth and attendant problems are indicative of metropolitan life in much of America today. Although the Triangle's short-term prospects are bright, Rohe warns that troubling issues loom-the region is expected to add nearly a million residents over the next two decades-and will need to be addressed through improvements in governmental cooperation, regional planning, and civic leadership. Finally, the author outlines key lessons that other metropolitan areas can learn from the Research Triangle's dramatic rise to prominence.

Heavenly Mathematics
Spherical trigonometry was at the heart of astronomy and ocean-going navigation for two millennia. The discipline was a mainstay of mathematics education for centuries, and it was a standard subject in high schools until the 1950s. Today, however, it is rarely taught.Heavenly Mathematicstraces the rich history of this forgotten art, revealing how the cultures of classical Greece, medieval Islam, and the modern West used spherical trigonometry to chart the heavens and the Earth. Glen Van Brummelen explores this exquisite branch of mathematics and its role in ancient astronomy, geography, and cartography; Islamic religious rituals; celestial navigation; polyhedra; stereographic projection; and more. He conveys the sheer beauty of spherical trigonometry, providing readers with a new appreciation for its elegant proofs and often surprising conclusions.
Heavenly Mathematicsis illustrated throughout with stunning historical images and informative drawings and diagrams that have been used to teach the subject in the past. This unique compendium also features easy-to-use appendixes as well as exercises at the end of each chapter that originally appeared in textbooks from the eighteenth to the early twentieth centuries.
