WebThe Cos θ = Adjacent / Hypotenuse. Cos angle formula. There are many formulas in trigonometry but there are few most important basic formulas in trigonometry when it comes to a right-angle triangle. The Cos theta or cos θ is the ratio of the adjacent side to the hypotenuse, where θ is one of the acute angles. The cosine formula is as follows: Webtan(x y) = (tan x tan y) / (1 tan x tan y). sin(2x) = 2 sin x cos x. cos(2x) = cos 2 (x) - sin 2 (x) = 2 cos 2 (x) - 1 = 1 - 2 sin 2 (x). tan(2x) = 2 tan(x) / (1 ...
