e functions sine, cosine and tangent of an angle are sometimes referred to as e pri y or basic trigonometric functions. eir usual abbreviations are sin(θ), cos(θ) and tan(θ), respectively, where θ denotes e angle. e paren eses around e argument of e functions are often omitted, e.g., sin θ and cos θ, if an interpretation is unambiguously possible. Trigonometry – Sin Cos Tan. Trigonometry – is e relationship between e sides and angles of triangles. Sin, cos and tan are abbreviations of sine, cosine and tangent, while ` eta` is e symbol used for an unknown angle, and is known as eta. `sin\ eta= (Opposite)/(Hypoten\use)`. is page explains e sine, cosine, tangent ratio, gives on an overview of eir range of values and provides practice problems on identifying e sides at are opposite and adjacent to a given angle. e Sine, Cosine and Tangent functions express e ratios of sides of a right triangle.Missing: dating. 6 Basically, Sin and Tan are ried and Cos is e bro er of Tan.
