Product aan som / verschil formule

COSX COZY = (1/2) [COS (X - Y) + COS (X + Y)]

SINX COZY = (1/2) [SIN (X + Y) + SIN (X - Y)]

COSX SINDY = (1/2) [SIN (X + Y) - SIN [(X - Y)]

SINX SINDY = (1/2) [COS (X - Y) - COS (X + Y)]

Bijvoorbeeld, wanneer u = 13 º, v = 17 º, zonde (13) zonde (17) = 0,065769, COS (13) COS (17) = 0.931795, zonde (13) COS (17) = 0,215122, COS (13 ) Zonde (17) = 0.284878.
