WebSine, 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 "Hypotenuse" is the long one WebThe sine function relates a real number \displaystyle t t to the y -coordinate of the point where the corresponding angle intercepts the unit circle. More precisely, the sine of an angle \displaystyle t t equals the y -value of the endpoint on the unit circle of an arc of length \displaystyle t t.
