COSX + COZY = 2COS [(x + y) / 2] COS [(x - y) / 2]
Sinx + Siny = 2sin [(x + y) / 2] COS [(x - y) / 2]
COSX - COZY = - 2SIN [(x + y) / 2] SIN [(X - Y) / 2]
SINX - SINDY = 2COS [(x + y) / 2] SIN [(X - Y) / 2]
Som / Difference to Product Trigonometry Identiteiten Berekening is handig en behulpzaam voor jou.
Bijvoorbeeld, wanneer x = 1º, y = 2º, zonde (1) + zonde (2) = 0,052352, zonde (1) - zonde (2) = -0.017447, COS (1) + COS (2) = 1.999239, COS (1) - COS (2) = 0,000457.
