In trigonometry trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined Geometrically these are identities involving certain functions of one or more angles They are distinct from triangle identities which are identities potentially involving angles but also involving side lengths Explanation So we have cos x sin x If we multiply it by two we have 2cos x sin x Which we can say it s a sum cos x sin x sin x cos x Which is the double angle formula of
