$\sin\left(3x\right)$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sin(3x)=3sin(x)-4sin(x)^3. Starting from the left-hand side (LHS) of the identity. Apply the trigonometric identity: \sin\left(3\theta \right)=3\sin\left(\theta \right)-4\sin\left(\theta \right)^3. Since we have reached the expression of our goal, we have proven the identity.
