What is rhumb line in geography?
Space and AstronomyIn navigation, a rhumb line, rhumb (/rʌm/), or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant bearing as measured relative to true north. What is a rhumb line used for? A Rhumb Line (also known as a loxodrome) is a line on the earth’s
Who was the most famous astronomer?
Space and AstronomyGalileo GalileiGalileo Galilei The astronomer (also mathematician, physicist and philosopher) turned the new observational tool toward the heavens, where he discovered the four primary moons of Jupiter (now known as the Galilean moons), as well as the rings of Saturn. Who was famous astronomers? If you’re interested in famous astronomers, you’ve likely heard of Copernicus,
How can you tell if a graph is acyclic?
Space and AstronomyTo test a graph for being acyclic: If the graph has no nodes, stop. The graph is acyclic. If the graph has no leaf, stop. The graph is cyclic. Choose a leaf of the graph. Remove this leaf and all arcs going into the leaf to get a new graph. Go to 1. What makes

Why is it called a manifold?
Space and AstronomyNomenclature. The term “manifold” comes from German Mannigfaltigkeit, by Riemann. In English, “manifold” refers to spaces with a differentiable or topological structure, while “variety” refers to spaces with an algebraic structure, as in algebraic varieties. What defines a manifold? manifold, in mathematics, a generalization and abstraction of the notion of a curved surface; a manifold
What is ref in sequence diagram?
Space and Astronomyref Reference: refers to an interaction defined on another diagram. The frame is drawn to cover the lifelines involved in the interaction. You can define parameters and a return value. What is ref in UML? To reference other interactions in a UML sequence diagram, interaction uses can be used. An interaction use is a fragment
What is the inverse of cos theta?
Space and Astronomy–1“>cos–1θ = cos–1[ (adjacent side) / (hypotenuse) ]. What is the inversion of Cos? Since cosine is the ratio of the adjacent side to the hypotenuse, the value of the inverse cosine is 30° , or about 0.52 radians. Is SEC inverse of cos? The secant function is a multiplicative inverse to the cosine function,
What is Trinomial expression?
Space and AstronomyWhat are trinomial expressions? A trinomial is an algebraic expression that has three non-zero terms. Examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z. 2a2 + 5a + 7 is a trinomial in one variables a. xy + x + 2y2 is a trinomial
What is transformation in math geometry?
Space and AstronomyTransformations. Transformation means to change. Hence, a geometric transformation would mean to make some changes in any given geometric shape. What is transformation mean in geometry? A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the
Who postulated the progressive wave theory of Tides?
Space and AstronomyWilliam WhewellWilliam Whewell. Who discovered tidal waves? Sir Isaac Newton’s Tides originate in the ocean and progress toward the coastlines, where they appear as the regular rise and fall of the sea surface. Thanks to Sir Isaac Newton’s 1687 discovery, we know that tides are very long-period waves that move through the ocean in response
