Write the right side of the identity as one fraction with the same denominator negative y−y.
Rewrite the numerator and the denominator separately. Distribute the terms of the numerator. Do not apply any trigonometric identities yet.
(cos (x-y)-cos x)/-y = cos x ((cos y -1)/(-y)) + sin x ((sin y)/(-y))
