Starting from the left-hand side (LHS) of the identity
$\frac{\sin\left(x\right)}{1-\cos\left(x\right)}$
Learn how to solve problems step by step online. Prove the trigonometric identity sin(x)/(1-cos(x))=cot(x/2). Starting from the left-hand side (LHS) of the identity. Multiply and divide the fraction \frac{\sin\left(x\right)}{1-\cos\left(x\right)} by the conjugate of it's denominator 1-\cos\left(x\right). Apply the trigonometric identity: 1-\cos\left(\theta \right)^2=\sin\left(\theta \right)^2. Simplify the fraction by \sin\left(x\right).
