Sin X Table. Функции y = sin x и y = cos x периодичны с периодом 2π. So, the table is drawn in.
Sin(x y) = sin x cos y cos x sin y. Cos(x y) = cos x cosy sin x sin y. Using the table we can find the values of sines and cosines of angles ranging from 0° to 90° at intervals of 1'.
For arguments outside those in the table, one may compute the corresponding information by using the periodicity.
