When we divide Sine by Cosine we get sin cos Opposite Hypotenuse Adjacent Hypotenuse Opposite Adjacent tan So we can say tan sin cos In mathematics sine and cosine are trigonometric functions of an angle The sine and cosine of an acute angle are defined in the context of a right triangle for the specified angle its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle the hypotenuse and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse Fo
