WebAnswer (1 of 2): Because when you have a vector, like force, the vector can be thought of as a right triangle. The complete vector is the hypotenuse, the vector can be decomposed into a horizontal component and a vertical component. By using trigonometry the vertical component is the opposite sid... WebThe main formula of cos θ is given by the ratio of base to the hypotenuse. There are several identities relating to cos θ and other trigonometric functions. These include: sin 2 θ + cos 2 θ = 1. cos θ = 1 / sec θ. cos θ = (1 – tan 2 θ /2) / (1 + tan 2 θ / 2) cos θ = sin θ * cot θ. cos (- θ) = cos θ. cos (90 – θ) = sin θ.
