The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. Throughout history, trigonometry has been applied in areas such as geodesy , surveying , celestial mechanics , and navigation. Trigonometry is known for its many identities. These trigonometric identities [5] [6] are commonly used for rewriting trigonometrical expressions with the aim to simplify an expression, to find a more useful form of an expression, or to solve an equation. Sumerian astronomers studied angle measure, using a division of circles into degrees. The ancient Nubians used a similar method.

This is the third of three articles on the History of Trigonometry. Part 2 Sections 5 - 7 can be found here. Part 1 Sections 1 - 4 can be found here. You, who wish to study great and wonderful things, who wonder about the movement of the stars, must read these theorems about triangles. Knowing these ideas will open the door to all of astronomy and to certain geometric problems.

Trigonometry , the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six 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. These six trigonometric functions in relation to a right triangle are displayed in the figure. For example, the triangle contains an angle A , and the ratio of the side opposite to A and the side opposite to the right angle the hypotenuse is called the sine of A , or sin A ; the other trigonometry functions are defined similarly.

Конечно, чтобы придать своему плану правдоподобность, Танкадо использовал тайный адрес… тайный ровно в той мере, чтобы никто не заподозрил обмана. Он сам был своим партнером. Никакой Северной Дакоты нет и в помине. Энсей Танкадо - единственный исполнитель в этом шоу. Единственный исполнитель.

Попытался что-то сказать, но голоса не. Зато был другой голос, тот, что звал .

В разговор вмешался новый участник. - Д-директор. Все повернулись к экрану. Это был агент Колиандер из Севильи.

Сьюзан пронзила ужасная мысль. Этой своей мнимой перепиской Танкадо мог убедить Стратмора в чем угодно. Она вспомнила свою первую реакцию на рассказ Стратмора об алгоритме, не поддающемся взлому. Сьюзан была убеждена, что это невозможно. Угрожающий потенциал всей этой ситуации подавил .
