Great-circle distance

calculating the haversine of the central angle between two points on a great circle of a sphere using the latitudes and the longitudes of the two points: sin2 (d2r) = sin2 ( Φ2 - Φ12) + cos (Φ1) cos (Φ2) sin2 ( λ2 - λ12) where Φ1 and Φ2 denote the latitudes of Singapore and Chicago respectively, and λ1 and λ2 denote the longitudes of Singapore and Chicago respectively. We can rearrange the haversine formula to give us the distance d between the two cities. 3.3 The Haversine function In order to

Introduction Long distance relationship, known as LDR is model of a romantic relationship that takes place when the partners are separated by significant distance. I have been experiencing this kind of relationship since 10 months ago and still going. As an international student studying abroad, my boyfriend and I separated within thousand miles between Indonesia and Australia. Although the time different is not far different and communication device is not a problem, deterioration still appears

airfare travel tips If you don 't take long-haul flights very often, everything about the experience can seem intimidating -- the interminable hours aloft, the sketchy choice of seats, choosing an airline you know nothing about, wondering if and how well you will be fed, dealing with boredom. And then there 's the pricing, which can put you back on your heels within seconds of clicking "Search for Flights." All told, a long-haul flight can be the most physically and financially demanding component

and its distance. ‒ My comment? What does it mean to me? a = angular size, expressed in seconds of arc. d = diameter of the object as d D = object’s distance ‒ What is it? A closer star will appear to move more than a more distant star. ‒ My comment? What does it mean to me? A closer star will

American Literature - Green 26 September 2017 Within the Circle Early in his narrative, Frederick Douglass stresses his lack of understanding and his absence of a personal history due to being enslaved. He begins by telling stories of his main home during his time as a slave: the Great House Farm. He focuses on the songs the slaves use to sing about the Great House Farm. While singing these songs, Douglass states about being “within the circle” (26). Frederick Douglass highlights his lack of a personal

the planets vs. their distances. · Get an overview of the solar system. · 50 points are possible Introduction It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable,

In the modern view of long-distance relationships, many immediately assume that the pairing will ultimately result in failure, with an eventual lack of love leading to a broken ending. This belief has largely existed throughout history, with multiple unions dissolved due to one spouse physically departing from the other. However, in John Donne’s Valediction: Forbidding Mourning, Donne presents a speaker in 1612 giving a farewell address to his lover to soothe her worries, emphasizing that the strength

Before we give you some suggestions as what to take to your journey, we must give you an overview of your trip and what it will be like. In the Inferno, there are nine circles, and you will visit all of them. Throughout the journey, your guide, Dante, will explain your locations, punishments for the sinners found in each of the circles, why the sinners are sent there, a brief explanation of some of the people you will encounter along the way, and an interview with some of these people, which you choose

Subsequent to the conquest of Egypt by Alexander the Great, the ancient Greeks established possibly the greatest center of learning at the time in Alexandria. Indeed, history purports that perhaps this great library rivaled even the great library in Athens, especially considering the fact that the Alexandrian library produced such significant mathematical figures as Archimedes and Euclid, the works of whom likely depended on the earlier works of great Greek mathematicians like Thales and Pythagoras (Lahanas

each other in the same way that water does. As water does not want to separate from itself in the space of the cylinder as described in the above experiment, a nail does not want to separate from itself, even if there is a great weight pulling on it. In the experiment, if too great a weight was applied, the glass broke, in the case of the nail, one can only assume that the equivalent of the glass shattering would perhaps be the nail bending, rather than snapping
