What is acyclic graph in data structure?
Space and AstronomyAn acyclic graph is a graph without cycles (a cycle is a complete circuit). When following the graph from node to node, you will never visit the same node twice. This graph (the thick black line) is acyclic, as it has no cycles (complete circuits). A connected acyclic graph, like the one above, is called

What is the biggest galaxy in the local group?
Space and AstronomyThe Andromeda GalaxyAndromeda Galaxy (M31), seen here in ultraviolet light, is the largest galaxy in the Local Group with some 1 trillion stars — roughly twice the population of our own Milky Way. Which is bigger galaxy or Local Group? The Andromeda Galaxy is the largest member of the Local Group, bigger even than our

What time did Neil Armstrong walk on the moon UK time?
Space and Astronomy3:56 a.m.3:56 a.m., 21 July, British time. His comments were interspersed with commentary from James Burke, often to fill in the silences. What time did Armstrong step on the Moon? Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC, and Armstrong became

How do you determine if a function crosses the horizontal asymptote?
Space and AstronomyThe graph of f can intersect its horizontal asymptote. As x → ± ∞, f(x) → y = ax + b, a ≠ 0 or The graph of f can intersect its horizontal asymptote. How do you know if a function crosses a horizontal asymptote? Video quote: If you can make the numerator of the

Do calla lilies mean death?
Space and AstronomyOn the one hand, calla lily meaning expresses the idea of life and fertility, while on the other it’s a well-known symbol of death. One early calla lily meaning originates in ancient Greek culture, where the flower was thought to represent magnificent beauty. This origin stems from a tale regarding Hercules as a baby. What

What is the formula of eccentricity?
Space and AstronomyEccentricity is basically the ratio of the distances of a point on the ellipse from the focus, and the directrix. If the distance of the focus from the center of the ellipse is ‘c’ and the distance of the end of the ellipse from the center is ‘a’, then eccentricity e = c/a. What is

What is the exterior of an angle?
Space and AstronomyThe Exterior Angle is the angle between any side of a shape, and a line extended from the next side. When we add up the Interior Angle and Exterior Angle we get a straight line 180°. They are “Supplementary Angles”. How do you find the exterior of an angle? Exterior Angles of a Regular Polygon

What is the derivative of f/g x ))?
Space and AstronomyThe chain rule states that the derivative of f(g(x)) is f'(g(x))⋅g'(x). In other words, it helps us differentiate *composite functions*. How do you find the derivative of f/g x? In this section we want to find the derivative of a composite function f(g(x)) where f(x) and g(x) are two differentiable functions. d dx f(g(x)) =

What is the Incenter of a triangle equidistant from?
Space and Astronomysidesthe sides of the triangle. That is, PI=QI=RI . The circle drawn with the incenter as the center and the radius equal to this distance touches all three sides and is called incircle or the inscribed circle of the triangle. Is the incenter of a triangle is equidistant from the vertices? The INCENTER of a
