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°. WebThe Siddhantas and the Aryabhatiya contain the earliest surviving tables of sine values and versine (1 − cosine) values, in 3.75° intervals from 0° to 90°, to an accuracy of 4 decimal places.
