Listen to this 10 times and you'll be brainwashed by the formulas of sine, cosine and tangent! Try it! sinθ = O/Hcosθ = A/Htanθ = O/A (First recorded in 12B i...
Opposite. Sine, Cosine and Tangent. The three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent.
