sinx⋅siny = [cos(x − y) − cos(x + y)]/2; Sum to Product Formulas. The combination of two acute angles A and B can be presented through the trigonometric ratios, in the below trigonometry formulas. sinx + siny = 2[sin((x + y)/2)cos((x − y)/2)] sinx − siny = 2[cos((x + y)/2)sin((x − y)/2)] cosx + cosy = 2[cos((x + y)/2)cos((x − y)/2)] The sum to product formula are expressed as follows: sin A + sin B = 2 sin [ (A + B)/2] cos [ (A - B)/2] sin A - sin B = 2 sin [ (A - B)/2] cos [ (A + B)/2] cos A - cos B = -2 sin [ (A + B)/2] sin [ (A - B)/2] cos A + cos B = 2 cos [ (A + B)/2] cos [ (A - B)/2] Sum to Product Formulas Proof.
