Using sine and cosine, it's possible to describe any (x, y) point as an alternative, (r,θ) point, where r is the length of a segment from (0,0) to the point and θ is the angle between that segment and the x-axis. this is called the polar coordinate system, and the conversion rule is (x, y) = (rcos(θ),rsin(θ but what are sin and cos

Hello! :)

Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: "Opposite" is opposite to the angle θ "Adjacent" is adjacent (next to) to the angle θ.
