- $\sin 3 x + \cos 3 x$

• A) \(2 \cos ^ { 2 } x \sin x + \sin x - 2 \sin ^ { 3 } x + \cos x - 4 \cos x \sin ^ { 2 } x\)
• B) \(2 \sin x \cos ^ { 2 } x + \cos x + 1 - \sin ^ { 2 } x + \cos x\)
• C) \(\sin x \cos ^ { 2 } x - \sin ^ { 3 } x + \cos ^ { 3 } x - \sin ^ { 2 } x \cos x\)
• D) \(2 \sin x \cos ^ { 2 } x + \sin ^ { 3 } x - \cos ^ { 3 } x - 2 \sin ^ { 2 } x \cos x\)
