Map of the Coral Sea. The Coral Sea is a small sea off the north east coast of Australia. It has Queensland on its west side and the islands of Vanuatu and New Caledonia on its east.On the north edge is the Solomon Islands, and in the south it joins the Tasman Sea. The Great Barrier Reef is in the Coral Sea.ustralia claims many of the islands as part of its 780,000 square kilometre Coral Sea Islands Territory. Most of them are small coral or sand islands, and only one has people living on it. This is Willis Island which is used as a weather station with a population of only four.
Coterminal angles are angles in coordinate plane that result out of rotation of the terminal side of angles in standard position. The angle in standard position has the vertex at the origin and one ray on the positive x -axis, which is called the initial side of the angle.
In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just 'cot'. Of the six possible trigonometric functions, cotangent, secant, and cosecant, are rarely used. In fact, most calculators have no button for them, and software function libraries do not include them. They can be easily replaced with derivations of the more common three: sin, cos and tan. Cotangent can be derived in two ways: The inverse cotangent function - arccot. For every trigonometry function such as cot, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. So the inverse of cot is arccot etc. When we see arccot A, we interpret it as the angle whose cotangent is A.
