cosx cozy = (1/2) [cos (x - y) + cos (x + y)]]
sinx cozy = (1/2) [pecat (x + y) + pecat (x - y)]]
COSX SINY = (1/2) [SIN (X + Y) - SIN [(X - Y)]
SINX SINY = (1/2) [COS (X - Y) - COS (X + Y)]
Per exemple, quan u = 13 º, v = 17 º, pecat (13) pecat (17) = 0.065769, cos (13) cos (17) = 0.931795, pecat (13) cos (17) = 0.215122, cos (13) ) Sin (17) = 0.284878.
