Exercise
$\frac{3}{4}\sin\:\left(x\right)-\sin\:^3\left(x\right)=\frac{1}{4}\sin\left(3x\right)$
Step-by-step Solution
Learn how to solve quadratic equations problems step by step online. Prove the trigonometric identity 3/4sin(x)-sin(x)^3=1/4sin(3x). Starting from the left-hand side (LHS) of the identity. Multiplying the fraction by \sin\left(x\right). Combine all terms into a single fraction with 4 as common denominator. Apply the trigonometric identity: \sin\left(\theta \right)^3=\frac{3\sin\left(\theta \right)-\sin\left(3\theta \right)}{4}.
