# Sin cube theta

Proof: To prove the triple-angle identities, we can write sin 3 θ \sin 3 \theta sin 3 θ as sin (2 θ + θ) \sin(2 \theta + \theta) sin (2 θ + θ). Then we can use the sum formula and the double-angle identities to get the desired form:

Sin cube theta+cos cube theta + 2 sin cos /cos square sin square=sec^2cosec^2 Prove this question - Math - Introduction to Trigonometry The trigonometric triple-angle identities give a relationship between the basic trigonometric functions applied to three times an angle in terms of trigonometric functions of the angle itself. From these formulas, we also have the following identities for Solve your math problems using our free math solver with step-by-step solutions.
