Āryabhaṭa's table was the first sine table ever constructed in the history of mathematics. [8] The now lost tables of Hipparchus (c. 190 BC – c. 120 BC) and Menelaus (c. 70–140 CE) and those of Ptolemy (c. AD 90 – c. 168) were all tables of chords and not of half-chords. [8] Āryabhaṭa's table remained as the standard sine table of ...
The hypotenuse is a constant dimension—(100 mm or 10 inches in the examples shown). The height is obtained from the dimension between the bottom of one roller and the table's surface. The angle is calculated by using the sine rule (a trigonometric function from mathematics). Some engineering and metalworking reference books contain tables ...

In the table below, the label "Undefined" represents a ratio : If the codomain of the trigonometric functions is taken to be the real numbers these entries are undefined , whereas if the codomain is taken to be the projectively extended real numbers , these entries take the value ∞ {\displaystyle \infty } (see division by zero ).
In mathematics, tables of trigonometric functions are useful in a number of areas. Before the existence of pocket calculators, trigonometric tables were essential for navigation, science and engineering. The calculation of mathematical tables was an important area of study, which led to the development of the first mechanical computing devices.
The crash sent the taxi careening onto the sidewalk, where the vehicle hit the 51-year-old woman and two men, 44 and 49. The woman was “pinned” against a fence by the vehicle, a police source said
The last column of the table has more significant figures than is justified. Example, for 60 degrees a jya of 2978' is compared to a "correct" value of 3438 times the sine of 60 degrees. But 3438 itself is an approximation to the radius of the circle with circumference of 21600.
Beck missed the second half of the game, and backup quarterback Gunner Stockton took over and led the Bulldogs to the win in overtime. That secured them a spot in the College Football Playoff and ...
