$\frac{\sin\left(x\right)}{1-\cos\left(x\right)}$
Learn how to solve problems step by step online. Prove the trigonometric identity (sec(x)+1)/tan(x)=sin(x)/(1-cos(x)). Starting from the right-hand side (RHS) 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 . Apply the trigonometric identity: 1-\cos\left(\theta \right)^2=\sin\left(\theta \right)^2. Simplify the fraction by \sin\left(x\right).
