Questionsin2x+sin2y=2sin(x+y)cos(xy)\sin 2x + \sin 2y = 2 \sin (x+y) \cos (x-y) Prove this using only the double angle formula, without using the sum-to-product identities.

Studdy Solution
We have successfully shown that sin2x+sin2y=2sin(x+y)cos(xy)\sin 2x + \sin 2y = 2 \sin (x+y) \cos (x-y) using only the double angle formula.
