cosx cozy = (1/2) [cos (x - y) + cos (x + y)]

Sinx Cosy = (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)]

Zum Beispiel, wenn u = 13 º, v = 17 º, sin (13) sin (17) = 0,065769, cos (13) cos (17) = 0.931795, sin (13) cos (17) = 0,215122, cos (13 ) SIN (17) = 0,284878.
