| 例句 | This is another case of sewing machines and umbrellas, the items in question being the eccentric 1960s modernism of the original building, a pavilion with a somewhat wonky paraboloid roof, and Pawson's minimalism. Designs of the Year 2012 ? review 2012-02-12T00:05:52Z He topped the whole thing off with a swooping, saddle-shaped roof — a hyperbolic paraboloid in design-speak — that gave it a distinct presence. A Mexico City Design Landmark, Reborn as Something Else 2023-06-13T04:00:00Z In Brasilia, where guards in archaic uniforms stand by his inverted paraboloid arches, he pulled off an improbable combination of ceremony and futurism. Oscar Niemeyer: an appreciation 2012-12-09T00:06:19Z Figure 4.6 The graph of the given function of two variables is also a paraboloid. Calculus, Volume 3 2016-03-30T00:00:00Z A satellite dish is shaped like a paraboloid of revolution. Algebra and Trigonometry 2015-02-13T00:00:00Z Nearby, 16 stark-white paraboloid beams supported the Metropolitan Cathedral of Brasília like a crown of thorns. How Brasília Turned Me On to Modern Architecture’s Sexy Side 2018-11-02T04:00:00Z Moscow’s 1929 constructivist planetarium combined a proletarian ethos with revolutionary engineering: a paraboloid dome in reinforced concrete. Planetariums and the rise of spectacular science It includes the hyperbolic paraboloid, or off-center pyramid, above. Donald Trump, Obama, Thanksgiving: Your Weekend Briefing 2016-11-20T05:00:00Z The coefficients of x2 and y2 are equal, so the cross-section of the paraboloid perpendicular to the z-axis is a circle. Calculus, Volume 3 2016-03-30T00:00:00Z A searchlight is shaped like a paraboloid of revolution. Algebra and Trigonometry 2015-02-13T00:00:00Z The 32-story building may resemble an off-center pyramid, but the architects prefer to describe it as a hyperbolic paraboloid. The New Shapes of New York 2016-11-17T05:00:00Z And yet there’s a way in which they’re truer to elliptic paraboloids and conic points than the models, for geometric surfaces and algebraic functions are not plaster concoctions. See How Man Ray Made Elliptic Paraboloids Sexy At This Phillips Collection Photography Exhibit 2015-02-13T05:00:00Z The roof reaches its highest point at either end and sags in the middle, until it forms what architects call a truncated hyperbolic paraboloid. Olympic Velodrome Is Known as ‘the Pringle’ 2012-08-01T17:02:36Z We first notice that the z term is raised only to the first power, so this is either an elliptic paraboloid or a hyperbolic paraboloid. Calculus, Volume 3 2016-03-30T00:00:00Z The hyperbolic paraboloid is also covered by two systems of rectilinear generators as a method like that used in � 34 establishes without difficulty. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 6 "Geodesy" to "Geometry" 2011-09-19T02:00:10.473Z Behind this was a curious, paraboloid projector made up of hundreds of tiny, carefully orientated coils. The Ultimate Weapon As to the paraboloid course pursued by the projectile, the resistance of the air is a factor which Galileo could not accurately compute, and which interferes with the practical realization of his theory. A History of Science — Volume 2 Find the volume of the solid situated in the first octant and bounded by the paraboloid z = 1 − 4x2 − 4y2 and the planes x = 0, y = 0, and z = 0. Calculus, Volume 3 2016-03-30T00:00:00Z Figure 4.5 A paraboloid is the graph of the given function of two variables. Calculus, Volume 3 2016-03-30T00:00:00Z Consequently a quadric surface is covered by two sets of straight lines, a pair through every point on it; these are imaginary for the ellipsoid, hyperboloid of two sheets, and elliptic paraboloid. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 6 "Geodesy" to "Geometry" 2011-09-19T02:00:10.473Z The result was a mirror that was so nearly a perfect paraboloid that the beam held sharp and absolutely tight for the half-mile range they tested it on. The Ultimate Weapon The lower bound for r is zero, but the upper bound is sometimes the cone and the other times it is the paraboloid. Calculus, Volume 3 2016-03-30T00:00:00Z What is the flux through just the paraboloid? Calculus, Volume 3 2016-03-30T00:00:00Z Figure 5.35 Finding the volume of a solid with a paraboloid cap and a circular base. Calculus, Volume 3 2016-03-30T00:00:00Z If it lies at the infinity, the plane at infinity is a tangent plane, and the surface is called a paraboloid. Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 6 "Geodesy" to "Geometry" 2011-09-19T02:00:10.473Z Therefore, we expect the surface to be an elliptic paraboloid. Calculus, Volume 3 2016-03-30T00:00:00Z Figure 5.36 Finding the volume of a solid under a paraboloid and above a given triangle. Calculus, Volume 3 2016-03-30T00:00:00Z The cone is the lower bound for z and the paraboloid is the upper bound. Calculus, Volume 3 2016-03-30T00:00:00Z Similarly, the equation of the paraboloid changes to z = 4 − r 2. Calculus, Volume 3 2016-03-30T00:00:00Z |
