Cosx Cozy = (1/2) [COS (X - Y) + COS (X + Y)]
SINX COZY = (1/2) [SIN (X + Y) + SIN (x - Y)]
Cosx Siny = (1/2) [SIN (X + Y) - SIN [(x - Y)]
Sinx Siny = (1/2) [COS (X - Y) - COS (X + Y)]
উদাহরণস্বরূপ, যখন আপনি = 13 º, v = 17 º, পাপ (13) পাপ (17) = 0.065769, COS (13) COS (17) = 0.931795, পাপ (13) COS (17) = 0.215122, COS (13) ) পাপ (17) = 0.284878।
