Triple Angle Identities | Brilliant Math & Science Wiki
To prove the triple-angle identities, we can write \sin 3 \theta sin3θ as \sin (2 \theta + \theta) sin(2θ +θ). Then we can use the sum formula and the double-angle identities to get the desired form:
List of trigonometric identities - Wikipedia
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.
