The sin and cos are called trigonometrical ratios. In a right angled triangle sin of an angle is defined as the ratio of Perpendicular with respect to the reference angle to it's Hypotenuse. Similarly cos of an angle is refined as the ratio of base of the triangle corresponding to the reference angle...
