Symbols representing Sin (center), Ishtar (left) and Shamash (right), as depicted on the upper half of a kudurru of Meli-Shipak II. Despite Sin's popularity documented in textual sources, depictions of him are not common in Mesopotamian art. [75] His most common attribute was the crescent.
In mathematics, sine and cosine are trigonometric functions of an angle.The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that ...
The term "trigonometry" was derived from Greek τρίγωνον trigōnon, "triangle" and μέτρον metron, "measure". [3]The modern words "sine" and "cosine" are derived from the Latin word sinus via mistranslation from Arabic (see Sine and cosine § Etymology).
Depiction of the sin of Adam and Eve (The Garden of Eden with the Fall of Man by Jan Brueghel the Elder and Pieter Paul Rubens) In religious context, sin is a transgression against divine law or a law of the deities. [1] Each culture has its own interpretation of what it means to commit a sin. While sins are generally considered actions, any ...
Basis of trigonometry: if two right triangles have equal acute angles, they are similar, so their corresponding side lengths are proportional.. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) [1] are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
Depiction of the sin of Adam and Eve (The Garden of Eden with the Fall of Man by Jan Brueghel the Elder and Pieter Paul Rubens). Original sin (Latin: peccatum originale) in Christian theology refers to the condition of sinfulness that all humans share, which is inherited from Adam and Eve due to the Fall, involving the loss of original righteousness and the distortion of the Image of God.

Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') [1] is a branch of mathematics concerned with relationships between angles and side lengths of triangles.
Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β.
