What direction should a sundial point?
Space and AstronomySundials need to point in the direction of True North, and the style (either a sharp straight edge or thin rod, often located at the edge or tip of the gnomon) must be aligned with the Earth’s rotational axis. Why does the sundial have to point north? All the hour-lines intersect at the point where
Which angles are corresponding angles?
Space and AstronomyIn geometry, corresponding angles are formed where a line known as an intersecting transversal, crosses through a pair of straight lines. Corresponding angles are the pairs of angles that are found in the same relative position on different intersections. What are corresponding angles examples? Corresponding angles are the angles that are formed when two parallel
What is sin of 90 minus theta?
Space and AstronomyWhat is sin 90 minus theta? Sin (90 – Theta) is equal to Cos Theta. What does 90 minus theta mean? Trigonometric ratios of 90 degree minus theta is one of the branches of ASTC formula in trigonometry. Trigonometric-ratios of 90 degree minus theta are given below. sin (90° – θ) = cos θ cos
What is a 6 inch radius?
Space and AstronomyWhat is the area of a 6 inch radius? Answer: The area of a circle with a diameter of 6 units is 28.27 sq. units or 9π square units. What is the radius of a 6 inch circumference? Circumference & Areas Size in Inches Circumference Inches Area in Square Inches 5 1/2 17.280 23.760 5
Who first used function notation?
Space and AstronomyThe term “function” was introduced by Gottfried Wilhelm Leibniz (1646-1716) almost fifty years after the publication of Geometry. The idea of a function was further formalized by Leonhard Euler (pronounced “oiler” 1707-1783) who introduced the notation for a function, y = f(x). Who invented function notation? Leonhard Euler The term “function” was then introduced by
Can planes be parallel?
Space and AstronomyPlanes are either parallel, or they’re perpendicular, otherwise they intersect each other at some other angle. parallel if the ratio equality is true. perpendicular if the dot product of their normal vectors is 0. Can two planes be parallel? In general, if two planes are parallel, then that means their normal vectors, 𝐧 one and
How do you translate a linear function horizontally?
Space and Astronomyhorizontal movement will ALWAYS be inside with the x added or subtracted and is OPPOSITE what you want. To move the function horizontally, place the number inside parenthesis and do the opposite of the way you want to move. To move left put a plus and your number and to move right put a minus
Can galaxies move faster than light?
Space and AstronomyUniversal expansion The expansion of the universe causes distant galaxies to recede from us faster than the speed of light, if proper distance and cosmological time are used to calculate the speeds of these galaxies. Do galaxies move towards or away from each other? On large scales, beyond the distances over which galaxies can interact
What does a space architect do?
Space and AstronomySpace architects create the schematics and blueprints for spaceships, satellites, orbiting telescopes, and other man-made structures that are launched beyond Earth’s atmosphere. Professionals research the latest advances in aerospace technology to create plans for efficient and safe rockets and vehicles. Can architects work in NASA? NASA’s human spaceflight architecture team spans the agency, with team
How do you use cosine rule with 3 sides?
Space and AstronomyHow do you use the law of cosines with 3 sides? Video quote: Minus 2 times 14 times 8 times the cosine of B 19 squared is going to be 361 equals 196 plus 64 and then 2 2 times 14 times 8 is going to be 224. Times the cosine of B. How do
