Deducing identities like the following:

tan(x±y) = \(\frac{\tan x \pm \tan y}{1 \mp \tan x \tan y}\)

cot(x±y) = \(\frac{\cot x \cot y \mp 1}{\cot y \pm \cot x}\)

sin x + sin y = 2 sin \(\frac{x+y}{2}\) cos \(\frac{x-y}{2}\)

sin x – sin y = 2 cos \(\frac{x+y}{2}\) sin \(\frac{x-y}{2}\)

cos x + cos y = 2 cos \(\frac{x+y}{2}\) cos \(\frac{x-y}{2}\)

cos x – cos y = -2 sin \(\frac{x+y}{2}\) sin \(\frac{x-y}{2}\)
