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.
Gen. 1:9 And God said, "Let the waters be collected". Letters in black, pointing in red, cantillation in blue [1] Hebrew orthography includes three types of diacritics: . Niqqud in Hebrew is the way to indicate vowels, which are omitted in modern orthography, using a set of ancillary glyphs.
Gardiner's sign list is a list of common Egyptian hieroglyphs compiled by Sir Alan Gardiner.It is considered a standard reference in the study of ancient Egyptian hieroglyphs.
Mathematical tables are lists of numbers showing the results of a calculation with varying arguments.Trigonometric tables were used in ancient Greece and India for applications to astronomy and celestial navigation, and continued to be widely used until electronic calculators became cheap and plentiful in the 1970s, in order to simplify and drastically speed up computation.
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 ).
