Remark If the angle is in degrees, either … Nettet12. des. 2024 · How does sin and cos work? Sine and cosine — a.k.a., sin (θ) and cos (θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin (θ) is the ratio of the opposite side to the hypotenuse , while cos (θ) is the ratio of the adjacent side to the hypotenuse . What is formula of cos?

While the early study of trigonometry can be traced to antiquity, the trigonometric functions as they are in use today were developed in the medieval period. The chord function was discovered by Hipparchus of Nicaea (180–125 BCE) and Ptolemy of Roman Egypt (90–165 CE). See in particular Ptolemy's table of chords.
