plane trigonometry造句

• In 1950 & ndash; 1951 the department expanded a little, offering 34 classes ranging from college algebra to analytic geometry to plane trigonometry.
• Some time shortly after 1946 however the department developed thirty-four additional courses in everything from collegiate algebra to analytic geometry and plane trigonometry.
• His books, " The Elements of Coordinate Geometry " and " Plane Trigonometry, " are also popular in India among students preparing for competitive exams.
• And this gives the answer to the first question; double algebra is nothing but analytical plane trigonometry, and this is why it has been found to be the natural analysis for alternating currents.
• Instead, the early Chinese used an empirical substitute known as " chong cha ", while practical use of plane trigonometry in using the sine, the tangent, and the secant were known.
• "Aryabhatiya " ends with spherical astronomy in " Gola ", where he applied plane trigonometry to sphericalgeometry by projecting points and lines on the surface of a sphere onto appropriate planes.
• These identities reduce to the cosine rule of plane trigonometry in the limit of sides much smaller than the radius of the sphere . ( On the unit sphere " a, b, c \ sin a \ approx a and \ cos a \ approx 1-a ^ 2 / 2 etc .; see Spherical law of cosines .)
• Culianu's textbooks include an 1870 one on differential and integral calculus, the first published Romanian-language course on mathematical analysis; and ones on elementary algebra ( 1872 ), applied geometry ( 1874 ), plane and spherical trigonometry ( 1875 ), cosmography ( 1893 ), plane trigonometry ( 1894 ) and high-school cosmography ( 1895 ).
• During his tenure of this chair he published two volumes of " A Course of Mathematics "-the first, entitled " Elements of Geometry, Geometrical Analysis and Plane Trigonometry ", in 1809, and the second, " Geometry of Curve Lines ", in 1813; the third volume, on " Descriptive Geometry and the Theory of Solids " was never completed.
• They include, " practical geometry and mathematics, particularly applied to the raising and transporting of heavy weights, the art of surveying and levelling, with their application to the conveying of water or draining morasses . . . the science of fortification in all its parts, with the manner of attacking and defending places, as likewise the use, conduct and direction of mines . . . the rudiments of military architecture, particularly the method of making plans, elevations and sections of powder magazines, guard rooms, barracks, storehouses, and other buildings that may be necessary in fortified towns . . . . the theory of artillery, viz . the doctrine of projectiles, so as to apply the same to gunnery, the principles on which the several pieces of ordnance and their carriages are constructed, and the method of forming exact draughts of the same, according to the tables used by the office of ordnance, likewise the names, uses and dimensions of all other engines and implements of war . . . . the principles of arithmetic, algebra, the elements of geometry, the mensuration of superfices and solids, plane trigonometry, the elements of conic sections, and the theory of perspective, as also geography and the use of globes . . . . the method of sketching ground, the taking of views, the drawing of civic architecture, and the practice of perspective . " Little wonder then that George Washington was found so capable of leading the Continental Army to victory over Great Britain in the American Revolutionary War.
