Will Halley’s comet ever stop?
Space and AstronomyIt will be decades until Halley’s gets close to Earth again in 2061, but in the meantime, you can see its remnants every year. How long will Halley’s comet last? In 1989, Boris Chirikov and Vitold Vecheslavov performed an analysis of 46 apparitions of Halley’s Comet taken from historical records and computer simulations. These studies
What are the advantages and disadvantages of point to point topology?
Space and AstronomyThe advantage of point-to-point network topology is that it is much simpler than mesh or star, because the topology simply tunnels a flow of data either unidirectionally or bidirectionally between two points. The disadvantage is that point-to-point networks are not very useful for IoT. What is a disadvantage of point-to-point topology? Disadvantages of Point to
How many trigonometric functions are there?
Space and Astronomysix functionssix functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). What are the 12 trig functions? The historical answer: At least 12 These are versine, haversine, coversine, hacoversine, exsecant, and excosecant. All of these can be expressed
How do you find the center of a circle in construction?
Space and AstronomyHow do you find the center of a circle using construction? Center of Circle Draw a line across the circle to make a “chord” Construct the perpendicular bisector of that chord to make a diameter of the circle. Construct the perpendicular bisector of that diameter to get the center of the circle. How do you
Which astronaut flew the most missions?
Space and AstronomyAstronauts Jerry Ross and Franklin Chang-Diaz have flown the most shuttle missions with seven each. What astronaut went on the most missions? Cosmonaut Gennady Padalka holds this record, with a little more than 878 days accrued over five spaceflights. That’s almost two and a half years (2 years 4 months 3 weeks 5 days) spent
What is the substitution axiom?
Space and AstronomyThe Substitution Axiom It states that if two quantities are equal, then one can be replaced by the other in any expression, and the result won’t be changed. What are the 4 axioms? AXIOMS Things which are equal to the same thing are also equal to one another. If equals be added to equals, the
When did Pioneer 10 have the closest approach to Jupiter?
Space and AstronomyDec. 4, 1973Dec. 4, 1973, NASA’s Pioneer 10 spacecraft sent back images of Jupiter of ever-increasing size. The most dramatic moment was after closest approach and after the spacecraft was hidden behind Jupiter. How long did it take Pioneer 10 to reach Jupiter? The first spacecraft to ever cross the gulf from the Earth to
How do you connect a function to the difference quotient?
Space and AstronomyThe steps we take to find the difference quotient are as follows: Plug x + h into the function f and simplify to find f(x + h). Now that you have f(x + h), find f(x + h) – f(x) by plugging in f(x + h) and f(x) and simplifying. Plug your result from step
What is the limit definition of continuity?
Space and AstronomyWhat is the definition of continuity in terms of limits? A function is continuous if it is unbroken fro all values of x. The formal definition states that f(x) is continuous if the limit as f(x) approaches a is equal to that of f(a). How do you find the limit of continuity? Key Concepts For
What is a segment in a circle?
Space and AstronomyA segment of a circle can be defined as a region bounded by a chord and a corresponding arc lying between the chord’s endpoints. In other words, a circular segment is a region of a circle which is created by breaking apart from the rest of the circle through a secant or a chord. What
