"Trigonometry" Quotes from Famous Books
 ... of land that was not for sale contains exactly eleven acres. Of course it is not difficult to find the answer if we follow the eccentric and tricky tracks of intricate trigonometry; or I might say that the application of a well-known formula reduces the problem to finding one-quarter of the square root of (4 x 370 x 116) -(370 116 - 74) squared—that is a quarter of the square root of 1936, which is one-quarter ...

... dark root together with the golden fruitage; whenever the nature of the case does not presume a contradistinction of the one to the other.] Religion, in the eye of a Pagan, had no more relation to morals, than it had to ship-building or trigonometry. But, then, why was religion honored amongst Pagans? How did it ever arise? What was its object? Object! it had no object; if by this you mean ulterior object. Pagan religion arose in no motive, but in an impulse. Pagan religion aimed at no distant prize ahead: ...

... above all things, sometimes disguised by affected languor, always well kept under by the laws of good-breeding,—but still it loves abundant life, opulent and showy organizations,—the spherical rather than the plane trigonometry of female architecture,—plenty of red blood, flashing eyes, tropical voices, and forms that bear the splendors of dress without growing pale beneath their lustre. Among these you will find the most delicious women you will ever meet,—women whom ...

... Roman numerals. In geometry the Arabs added little to Euclid, but algebra is practically their creation. An Arabic treatise on algebra long formed the textbook of the subject in the universities of Christian Europe. Spherical trigonometry and conic sections are Arabic inventions. This mathematical knowledge enabled the Arabs to make considerable progress in astronomy. Observatories at Bagdad and Damascus were erected as early as the ninth century. Some of the astronomical instruments ...

... Carlo, where he had been spending a few days in the interests of science, and presented your letter of introduction. Said he still couldn't understand just how it happened, because he had figured it out by logarithms and trigonometry and differential calculus and a lot of other high-priced studies that he'd taken away from Harvard, and that it was a cinch on paper. Was so sure that he could have proved his theory right if he'd only had a little ...

... trigonometry the Arabians, by the introduction of the use of the sine, or half-chord, of the double arc in the place of the arc itself, made great advancement, especially in the calculations of surveying and astronomy. In the universities and colleges of Spain under ...

... to decipher his steward's hieroglyphics, favoured by the same light, and the captain of marines was examining the lock of an aged musket. The third and fourth lieutenants were helping each other to untangle one of their Bay-of-Biscay reckonings, which had set both plane and spherical trigonometry at defiance, by a lamp of their own; and the chaplain was hurrying the steward and the boys along with the breakfast—his usual occupation at that "witching ...

... poor in mathematics can learn something about geometry, algebra, and trigonometry; even he who "has no head for language" can learn to speak a foreign tongue and even to read Latin or Greek. It is not easy for either one of them and perhaps the one can never become a great mathematician nor the other a great linguist, but both ...

... Betelgeuse up there, which Michelson has been able to measure. He has, at least, succeeded in measuring the angle at the eye that Betelgeuse subtends, so that after estimating its parallax as given by a heliometer, it's merely a matter of trigonometry to work out the size of the star. And he estimated Betelgeuse to be two hundred and sixty million miles in diameter. That means it would take twenty-seven million of our suns to equal it in bulk. So that this big world of ours, ...

... languages and all the facts about the Arctic regions, and the history of dancing from the days of Old Adam down to those of Old Nick, he couldn't write up a satisfactory account of the Ice-Men's Ball. Could prove that two and two made four by trigonometry and geometry, but couldn't learn to keep books; was thick as thieves with all the high-toned poets, but couldn't write a good, snappy, merchantable street-car ad.; knew a thousand diseases that would take a man off before he could blink, but couldn't sell ...

... "In spherical trigonometry," he concluded, "to solve the problem three elements must be known. I knew four. Therefore I could take each of the known, treat it as unknown, and have four ways to check my result. I find that the time might have been ...

... but her advice to me was, not to omit anything because I did not like it. I had a natural distaste for mathematics, and my recollections of my struggles with trigonometry and conic sections are not altogether those of a conquering heroine. But my teacher told me that my mind had need of just that exact sort of discipline, and I think ...

... must be a sketch or lineation of something—but of what? or of what kind of thing? It might be of the fields constituting a property; it might be of the stones in a wall; it might be of an irregular mosaic; or perhaps it might be only a school-boy's exercise in trigonometry for land-measuring. It must mean something; but it could hardly mean anything of consequence to anybody! Still it had been the old captain's probably—or perhaps the old lord's: he would replace it also where he had found ...

... difference between an acute angle and a right angle is termed the complement of the angle, and between an angle and two right angles the supplement of the angle. The generalized view of angles and their measurement is treated in the article TRIGONOMETRY. A solid angle is definable as the space contained by three or more planes intersecting in a common point; it is familiarly represented by a corner. The angle between two planes is termed dihedral, between three trihedral, ...
