Newton's three laws of motion describe the relationship between an object's motion and the forces acting on it. The first law states that an object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction, unless acted upon by an unbalanced force. The second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma). The third law states that for every actio

Sin, cos, and tan are the fundamental trigonometric ratios used in right-angled triangles to relate angles and side lengths. They are defined as follows: Sin (Sine): The ratio of the length of the opposite side to the length of the hypotenuse. Cos (Cosine): The ratio of the length of the adjacent side to the length of the hypotenuse. Tan (Tangent): The ratio of the length of the opposite side to the length of the adjacent side. These ratios are often written as sin(x), cos(x), and tan(x), where
