WebFor one specific angle a, e.g. a = 30° the three basic trigonometry functions – Sine, Cosine and Tangent, are ratios between the lengths of two of the three sides: Sine: sin (a) = Opposite / Hypotenuse. Cosine: cos (a) = Adjacent / Hypotenuse. Tangent: tan (a) = Opposite / Adjacent. That is all good when angle a is between 0° and 90°.
