Sine Function Formula In a right angled triangle the sine of an angle is equal to the ratio of side opposite to the angle also called perpendicular and hypotenuse Suppose is the angle in a right triangle ABC Then the sine formula is given by Sin Opposite side Hypotenuse or The classical definition of the sine function for real arguments is: "the sine of an angle in a right‐angle triangle is the ratio of the length of the opposite leg to the length of the hypotenuse." This description of is valid for when the triangle is nondegenerate.

How Does The Sine Function WorkSine, 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 to (next to) the angle θ. "Hypotenuse" is the long one. The amplitude A is the distance measured from the y value of a horizontal line drawn through the middle of the graph or the average value to the y value of the highest point of the sine curve and B is the number of times the
