Tangent Sin Over Cos. Sine cosine and tangent. Sine cosine and tangent often shortened to sin cos and tan are each a ratio of sides of a right angled triangle.
The sine of one of the angles of a right triangle often abbreviated sin is the ratio of the length of the side of the triangle opposite the angle to the length of the triangle s hypotenuse. The cosine often abbreviated cos is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. Lim x 0 sin x sin 0 0 lim x 0 cos x cos 0 1.
